It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0081] The embodiments of the present application provide a voucher cancellation method, device, server and storage medium, which are described in detail below.

[0082] See also Figure 1 , Figure 1 The scenario diagram of the method for revoking vouchers provided in the embodiment of the present application is shown in FIG. The method for revoking vouchers can be applied to a system for revoking vouchers. The system for revoking vouchers includes a user terminal 102 and a server 104. The user terminal 102 can be a desktop terminal or a mobile terminal. The mobile terminal can be at least one of a mobile phone, a tablet computer, and a laptop computer. The server 104 can be implemented as an independent server or a server cluster composed of multiple servers. The user terminal 102 and the server 104 can establish a communication connection through a wide area network, a metropolitan area network, or a local area network.

[0083] like Figure 2 As shown, in one embodiment, a method for writing off a voucher is provided. This embodiment mainly applies the method to the above Figure 1 The server 104 in FIG. Figure 2 The method for writing off the voucher specifically includes the following steps:

[0084] S201. Obtain a cancellation request from a user, wherein the cancellation request includes user information.

[0085] In the embodiment of the present application, the user may send the user's cancellation request through the user terminal 102. The user information may include customer code information and customer contract type information.

[0086] S202. Obtain information on outstanding items to be written off and information on clearing strategies for writing off outstanding items based on user information.

[0087] Each entry is stored in the form of a voucher, and each voucher is retained in the system as a consistent unit until it is archived. Each voucher consists of a voucher header and two or more line items. The voucher header refers to the information valid for the entire voucher, such as four dates, text summary, voucher type, etc. Line items only contain information about specific items, such as accounting code, account code, amount, tax code, cost object, etc., which are determined by the configuration of account, accounting code, etc.

[0088] In the embodiment of the present application, the user's outstanding item information is screened out from the business database based on the user information. Each item of data in the outstanding item information may include the voucher number, item number, sub-item number, company code, settlement agreement, customer code, creation date, transaction amount, local currency amount, group currency amount, etc. Specifically, when the user conducts a transaction, each transaction data will be stored in the business database. The transaction data is the data before the voucher is officially posted, which can also be called the pre-voucher.

[0089] Further, clearing strategy information of the uncleared item information is determined based on the user information. The clearing strategy information may be a clearing variant. The clearing variant corresponds to the user information, and the user may customize the setting according to the needs. Specifically, the clearing strategy information may include clearing features and sorting features. For example, the clearing features may be customer codes and settlement agreements, and the sorting features may be creation dates. The clearing features are used as filtering conditions; the sorting features are used to determine the order of data items during use. For example, data with features such as customer codes or creation dates are filtered out from the uncleared item information to form clearable item information.

[0090] S203. Generate clearable item information according to the clearing strategy information and the uncleared item information.

[0091] In the embodiment of the present application, the uncleared item information is screened according to the clearing strategy information to obtain the clearable item information. Each item of data in the clearable item information can be marked with a clearing characteristic value and a sorting characteristic value while screening, and the clearing characteristic value and sorting characteristic value of each item of data in the clearable item information can be obtained. For example, there are three items of data in the marked clearable item information, each of which has a [customer code] field, a [settlement agreement] field, and a [creation time] field. The customer code value in the first item of the clearable item information is 001, the settlement agreement value is 003, and the creation time value is 20200501; the customer code value in the second item of data is 002, the settlement agreement value is 004, and the creation time is 20200515. The customer code value in the third item of data is 001, the settlement agreement value is 004, and the creation time value is 20200401. Here, [customer code] and [creation time] can be used as clearing characteristics, and [creation time] can be used as sorting characteristics.

[0092] S204. Group the clearable item information according to preset clearing characteristic information to obtain a plurality of group clearing data.

[0093] In the embodiment of the present application, the preset account clearing characteristic information is input by the user and customized according to the user's needs. For example, the preset account clearing characteristic information can be a combination of a settlement agreement value and a customer code value, and the data with a settlement agreement value of 001 and a customer code value of 002 in the clearable item information is used as one group of account clearing data, and the data with a settlement agreement value of 002 and a customer code value of 002 in the clearable item information is used as another group of account clearing data.

[0094] S205: Perform write-off matching and comparison on multiple group clearing data to obtain write-off information.

[0095] like Figure 3 As shown, in one embodiment, multiple group clearing data are compared and matched to obtain the write-off information, which specifically includes the following steps:

[0096] S301. Divide each group of clearing data into first clearing group data and first cleared group data according to transaction virtual resource information in the group clearing data.

[0097] Specifically, the transaction virtual resource information is the transaction amount of the transaction data. For example, the transaction amount is 10 yuan, -10 yuan, etc. The data with negative transaction amounts in the grouped clearing data are determined as the first clearing group data, and the data with positive transaction amounts in the grouped clearing data are determined as the first cleared group data. For example, there are three data in the first clearing group data, and the transaction amounts of the three data are -80 yuan, -100 yuan, and -50 yuan respectively. There are three data in the first cleared group data, and the transaction amounts of the three data are 80 yuan, 90 yuan, and 50 yuan respectively.

[0098] S302 . Sort the first clearing group data and the first cleared group data respectively according to preset sorting characteristic information to obtain the second clearing group data and the second cleared group data.

[0099] In an embodiment of the present application, the preset sorting feature information is input by the user, for example, the sorting feature information includes sorting features and sorting logic, which can be customized by the user. For example, the sorting feature is [transaction amount], and the sorting logic is to sort from large to small by the absolute value of the transaction amount. The first account clearing group data is sorted according to the preset sorting feature information to obtain the second account clearing group data, that is, the sorted first account clearing group data. The first account clearing group data is sorted according to the preset sorting feature information to obtain the second account clearing group data, that is, the sorted first account clearing group data. For example, the transaction amounts in the second account clearing group data obtained by sorting the first account clearing group data and the first account clearing group data are: -100 yuan, -80 yuan, and -50 yuan, respectively. The transaction amounts of the obtained second account clearing group data are: 90 yuan, 80 yuan, and 50 yuan, respectively.

[0100] S303: Perform write-off matching and comparison on the second account clearing group data and the second account cleared group data under the grouped account clearing data to obtain write-off information.

[0101] like Figure 4 As shown, in one embodiment, performing write-off matching and comparison on the second clearing group data and the second cleared group data under the grouped clearing data to obtain write-off information specifically includes the following steps:

[0102] S401 . Acquire clearing virtual resource information of the second clearing group data and cleared virtual resource information of the second cleared group data according to transaction virtual resource information of the second clearing group data, transaction virtual resource information of the second cleared group data, and clearing virtual resource type.

[0103] In the embodiment of the present application, the transaction virtual resource information is the transaction amount. The clearing virtual resource type is the clearing currency, which can be RMB, USD, EUR, etc. Specifically, the base currency of the first item of data in the second clearing group data is determined as the clearing currency. Specifically, the clearing virtual resource type is obtained from the second clearing group data, and the clearing virtual resource value is obtained according to the clearing virtual resource type and the transaction virtual resource value.

[0104] Furthermore, the clearing amount and the corresponding conversion rate are obtained according to the transaction amount of each data item in the second clearing group data, the transaction amount of each data item in the second cleared group data, and the clearing currency. The conversion logic is as follows:

[0105] By inputting [From Currency]=the transaction currency in the item to be cleared, [To Currency]=the clearing currency in the item to be cleared, [From Currency Amount]=the transaction amount in the item to be cleared, and Foreign Currency Conversion Date = [Posting Date] in the 《Automatic Clearing Identification Table》. Invoke the method <exchangeCurrency Convert Currency> in the class {CurrencyController Currency}, and obtain the return values [To Currency Amount] and [Exchange Rate], which are used as the current [Clearing Amount] and the corresponding [Exchange Rate] for each item to be cleared.

[0106] Furthermore, obtain the virtual resource value in the local currency at the clearing point based on the clearing virtual resource value and the transaction virtual resource value.

[0107] Specifically, obtain the [Local Currency Amount at Clearing Point] and the corresponding conversion [Exchange Rate] based on the [Clearing Amount]. The conversion logic is as follows:

[0108] By inputting [From Currency]=(clearing currency) in the item to be cleared, [To Currency]=(local currency) in the item to be cleared, [From Currency Amount]=(clearing amount) in the item to be cleared, and [Foreign Currency Conversion Date]=[Posting Date] in the 《Automatic Clearing Identification Table》, invoke the method <exchangeCurrency Convert Currency> in the class {CurrencyController Currency}, and obtain the return values [To Currency Amount] and [Exchange Rate], which are used as the current [Local Currency Amount at Clearing Point] and the corresponding [Exchange Rate] for each item to be cleared.

[0109] Furthermore, obtain the virtual resource value in the group currency at the clearing point based on the virtual resource value in the local currency at the clearing point. Specifically, the virtual resource value in the local currency is [Local Currency Amount at Clearing Point], and the virtual resource value in the group currency at the clearing point is [Group Currency Amount at Clearing Point].

[0110] Convert the [Local Currency Amount at Clearing Point] to the [Group Currency Amount at Clearing Point] and the corresponding conversion [Exchange Rate]. The conversion logic is as follows:

[0111] By inputting [From Currency]=(local currency) in the item to be cleared, [To Currency]=(group currency) in the item to be cleared, [From Currency Amount]=(Local Currency Amount at Clearing Point) in the item to be cleared, and [Foreign Currency Conversion Date]=[Posting Date] in the 《Automatic Clearing Identification Table》, invoke the method <exchangeCurrency Convert Currency> in the class {CurrencyController Currency}, and obtain the return values [To Currency Amount] and [Exchange Rate], which are used as the current [Group Currency Amount at Clearing Point] and the corresponding [Exchange Rate] for each item to be cleared.

[0112] After obtaining the account clearing virtual resource value, the account clearing time local currency virtual resource value, and the account clearing time group currency virtual resource value, the account clearing virtual resource value, the account clearing time local currency virtual resource value, and the account clearing time group currency virtual resource value are added to multiple group clearing data.

[0113] S402: Perform write-off matching and comparison on the second clearing group data and the second cleared group data according to the clearing virtual resource information and the cleared virtual resource information to obtain write-off information.

[0114] like Figure 5 As shown, in one embodiment, according to the clearing virtual resource information and the cleared virtual resource information, the second clearing group data and the second cleared group data are compared and written off to obtain the write-off information, including the following steps:

[0115] S501: Determine whether the absolute value of the first item of clearing virtual resource value in the clearing virtual resource information is equal to the absolute value of the first item of clearing virtual resource value in the cleared virtual resource information.

[0116] The clearing virtual resource information includes a plurality of clearing virtual resource values; the cleared virtual resource information includes a plurality of clearing virtual resource values. The clearing virtual resource value may be a clearing amount. For example, the clearing virtual resource value in the clearing virtual resource information is: -100 yuan, -80 yuan, -50 yuan. The clearing virtual resource values ​​of the second cleared group data obtained are: 90 yuan, 80 yuan, 50 yuan respectively.

[0117] Specifically, if the absolute value of the first clearing virtual resource value in the clearing virtual resource information is equal to the absolute value of the first clearing virtual resource value in the cleared virtual resource information, S502 is executed; if the absolute value of the first clearing virtual resource value in the clearing virtual resource information is not equal to the absolute value of the first clearing virtual resource value in the cleared virtual resource information, S504 is executed.

[0118] S502: If the absolute values ​​of the first clearing virtual resource value in the clearing virtual resource information and the first clearing virtual resource value in the cleared virtual resource information are equal, a write-off relationship is established between the first clearing virtual resource value in the second clearing group data and the first clearing virtual resource value in the second cleared group data.

[0119] For example, the first clearing virtual resource value of the second clearing group data is -100 yuan, and the first clearing virtual resource value of the second cleared group data is 100 yuan. A write-off relationship is established between the first clearing virtual resource value in the second clearing group data and the first clearing virtual resource value in the second cleared group data.

[0120] S503: Compare and write off the second clearing virtual resource value of the second clearing group data with the second clearing virtual resource value of the second cleared group data. The process of comparing and writing off the second clearing virtual resource value of the second clearing group data with the second clearing virtual resource value of the second cleared group data may refer to S501.

[0121] S504. If the absolute values ​​of the first clearing virtual resource value in the clearing virtual resource information and the first clearing virtual resource value in the cleared virtual resource information are not equal, determine whether the absolute value of the first clearing virtual resource value in the clearing virtual resource information is greater than the absolute value of the first clearing virtual resource value in the cleared virtual resource information.

[0122] S505. If the absolute value of the first account clearing virtual resource value in the account clearing virtual resource information is greater than the absolute value of the first account clearing virtual resource value in the account clearing virtual resource information, the first account clearing virtual resource value in the account clearing virtual resource information is split into a first sub-account clearing virtual resource value and a second sub-account clearing virtual resource value, wherein the sum of the first sub-account clearing virtual resource value and the first account clearing virtual resource value in the account clearing virtual resource information is equal to zero.

[0123] For example, if the first clearing virtual resource value in the clearing virtual resource information is -100 yuan, and the first clearing virtual resource value in the cleared virtual resource information is 90 yuan, the first clearing virtual resource value in the clearing virtual resource information is split into a first sub-clearing virtual resource value and a second sub-clearing virtual resource value, which are -90 yuan and -10 yuan respectively.

[0124] Further, in S504, if it is determined that the absolute value of the first account clearing virtual resource value in the account clearing virtual resource information is not greater than the absolute value of the first account clearing virtual resource value in the account clearing virtual resource information, the first account clearing virtual resource value in the account clearing virtual resource information is split into a third sub-account clearing virtual resource value and a fourth sub-account clearing virtual resource value, wherein the sum of the third sub-account clearing virtual resource value and the first account clearing virtual resource value in the account clearing virtual resource information is equal to zero. A write-off relationship is established between the third sub-account clearing virtual resource value and the first account clearing virtual resource value in the account clearing virtual resource information. The fourth sub-account clearing virtual resource value is compared with the second account clearing virtual resource value in the account clearing virtual resource information for write-off matching.

[0125] S506: Establish a write-off relationship between the first sub-clearing virtual resource value and the first clearing virtual resource value in the cleared virtual resource information.

[0126] S507: Compare and match the second sub-account clearing virtual resource value with the second item of account clearing virtual resource value in the account clearing virtual resource information.

[0127] It should be noted that according to the splitting strategy of Clearing Amount, Transaction Amount, Local Currency Amount, Group Currency Amount, Local Currency Amount at Clearing Time, and Group Currency Amount at Clearing Time are split according to the same period of Clearing Amount. During the amount splitting process, it is necessary to ensure that the sum of the amount of the original voucher item before and after the split is consistent. If there is an inconsistency due to the difference in decimal places, the difference needs to be added to the remaining amount item after the split.

[0128] If there are clearable items in the other set of data that can be used for further comparison after the remaining amount entry is newly separated, all fields of the newly separated remaining amount entry except the amount field will be assigned the same field values ​​as the original entry.

[0129] When the newly lent remaining amount continues to participate in the clearing and write-off matching comparison, the Local Currency Amount and Group Currency Amount in the item participating in the clearing comparison need to be compared with the Local Currency Amount and Group Currency Amount remaining before the item participates in the comparison again:

[0130] If the absolute value of the local currency amount involved in the clearing comparison is greater than the absolute value of the local currency amount remaining before the comparison, the local currency amount involved in the clearing comparison will be replaced with the local currency amount remaining before the comparison.

[0131] If the absolute value of the Group Currency Amount involved in the clearing comparison is greater than the absolute value of the Group Currency Amount remaining before the comparison, the Group Currency Amount involved in the clearing comparison will be replaced with the Group Currency Amount remaining before the comparison.

[0132] After the above two amount replacement processes, if the item continues to participate in subsequent clearing due to incomplete clearing of the transaction amount, the local currency amount for each clearing will be 0;

[0133] If there is no clearable item in the other set of data for further comparison after the remaining amount item is newly separated, the [Sub-item Number] of the newly separated remaining amount item = the maximum [Sub-item Number] of the original item + 1, and the [Previous Sub-item Number] = the [Sub-item Number] of the original item. Except for all amount fields, other fields are assigned exactly the same field values ​​as the original item.

[0134] For example, Company Code 1 is the company code in the second clearing group data, and Company Code 2 is the company code in the second cleared group data. In the write-off information, for entries where Company Code 1 and Company Code 2 are not empty, subtract Local Currency Amount 1 from Local Currency Amount 1 at Clearing Time for each entry, and assign the result to the corresponding Local Currency Exchange Difference 1; subtract Local Currency Amount 2 from Local Currency Amount 2 at Clearing Time for each entry, and assign the result to the corresponding Local Currency Exchange Difference 2;

[0135] Then subtract the Group Currency Amount 1 and the Group Currency Amount 1 at the Time of Clearing for each data item, and assign the result to the corresponding Group Currency Exchange Difference 1. Subtract the Group Currency Amount 2 and the Group Currency Amount 2 at the Time of Clearing for each data item, and assign the result to the corresponding Group Currency Exchange Difference 2.

[0136] If both Company Code 1 and Company Code 2 in the write-off information are not empty and the values ​​of the two fields are different, the value of the Cross-account Set Identifier field is set to Yes (1), otherwise the value is set to No (0).

[0137] Furthermore, after performing write-off matching and comparison on a plurality of group clearing data to obtain write-off information, the following steps are also included:

[0138] (1) Acquire the split second clearing group data, split information of the second clearing group data, split second cleared group data, and split information of the second cleared group data from the write-off information.

[0139] In the embodiment of the present application, the write-off information includes the split second account clearing group data, the split information of the second account clearing group data, the split second account cleared group data, and the split information of the second account cleared group data. The split second account clearing group data and the split second account cleared group data can be combined to obtain the "Account Clearing Matching Comparison Result Table". The split information of the second account clearing group data includes whether each account clearing amount in the second account clearing group data is split. The split information of the second account cleared group data includes whether each account clearing amount in the second account cleared group data is split.

[0140] (2) Classifying the write-off information into different voucher items based on the split second clearing group data, the split information of the second clearing group data, the split second cleared group data, and the split information of the second cleared group data.

[0141] The voucher includes the voucher customer details and the voucher general ledger details. The process before the voucher is officially posted is defined as the pre-voucher, which is mainly used to verify the data standardization before the voucher is officially posted. The pre-voucher includes the pre-voucher customer details and the pre-voucher general ledger details. For example, the pre-voucher customer details are in the Pre-voucher Customer Details table, and the pre-voucher general ledger information is in the Pre-voucher General Ledger Details table.

[0142] 1) Classify the data with Company Code 1 or Company Code 2 blank in the Account Clearing Matching Comparison Result Table as the second voucher item in the customer details of the preceding voucher.

[0143] Assign the write-off information according to the requirements of the second voucher item.

[0144] 2) In the Clearing Matching Comparison Result Table, the data where both Company Code 1 and Company Code 2 are not empty and the clearing amount in the entry is not split is classified as the third voucher item.

[0145] Assign the write-off information according to the requirements of the third voucher item.

[0146] 3) In the Clearing Matching Comparison Result Table, if both Company Code 1 and Company Code 2 are not empty and the data from which the clearing amount is split in the comparison item is classified as the sixth voucher item.

[0147] 4) Re-assign values ​​to the items categorized as the third credential item and the sixth credential item above.

[0148] 5) Classify the voucher items with [Booking Type] = (Clearing Exchange Difference) in the table "Previous Voucher General Ledger Details". Assign the write-off information according to the requirements of the voucher items with [Booking Type] = (Clearing Exchange Difference) in the table "Previous Voucher General Ledger Details".

[0149] 6) Classify the voucher items with [Booking Type] = (Payment or Clearing Internal Transactions) in the table of [Pre-Voucher General Ledger Details]:

[0150] When the [Cross-account set identifier] of a record in the "Account Clearing Matching Comparison Result Table" = 1, it means that the clearing comparison is across account sets, and the general ledger voucher items for internal transactions across account sets need to be accounted for. Note: the general ledger voucher items for internal transactions across account sets must appear in pairs, with opposite amounts, and the trading partners need to be accounted for.
