DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the embodiment.

[0016] [1. Overview] For example, in the wholesale industry, which handles a wide variety of products, there is a business practice of limiting the customers to whom a product may be sold depending on whether or not the product has a contract with a manufacturer. Here, the wholesale industry includes various wholesale industries such as beauty and hair care product wholesale, food wholesale, building material wholesale, retail wholesale, chemical product wholesale, pharmaceutical wholesale, and machine and equipment wholesale.

[0017] However, conventional systems do not allow for the restriction of the customers to whom a product can be sold.

[0018] Therefore, in this embodiment, when an order for a product is entered (when an order slip is recorded), sales restrictions (input restrictions) are imposed for each customer according to the manufacturer that produced the product or the group of the product.

[0019] This embodiment is applicable to various wholesale industries such as beauty and hair products wholesale, food wholesale, building materials wholesale, retail wholesale, chemical products wholesale, pharmaceutical wholesale, and machine and equipment wholesale.

[0020] [2. Configuration] An example of a sales restriction device according to the present embodiment will be described with reference to Fig. 1. Fig. 1 is a block diagram showing an example of the configuration of a sales restriction device according to the present embodiment.

[0021] The sales restriction device 100 is, for example, a commercially available desktop personal computer. The sales restriction device 100 is not limited to a stationary information processing device such as a desktop personal computer, but may be a portable information processing device such as a commercially available notebook personal computer, a PDA (Personal Digital Assistant), a smartphone, or a tablet personal computer. In FIG. 1, the sales restriction device 100 includes a control unit 102, a communication interface unit 104, a storage unit 106, and an input / output interface unit 108. The units included in the sales restriction device 100 are connected to each other so as to be able to communicate with each other via any communication path.

[0022] The communication interface unit 104 communicatively connects the sales restriction device 100 to the network 300 via a communication device such as a router and a wired or wireless communication line such as a dedicated line. The communication interface unit 104 has a function of communicating data with other devices via the communication line. Here, the network 300 has a function of connecting the sales restriction device 100 and the server 200 to each other so that they can communicate with each other, and is, for example, the Internet or a LAN (Local Area Network).

[0023] An input device 112 and an output device 114 are connected to the input / output interface unit 108. The output device 114 may be a monitor (including a home television), a speaker, or a printer. The input device 112 may be a keyboard, a mouse, a microphone, or a monitor that cooperates with a mouse to realize a pointing device function. In the following, the output device 114 may be referred to as a monitor 114.

[0024] Various databases, tables, files, etc. are stored in the storage unit 106. Computer programs for cooperating with an OS (Operating System) to give instructions to a CPU (Central Processing Unit) to perform various processes are recorded in the storage unit 106. For example, memory devices such as RAM (Random Access Memory) and ROM (Read Only Memory), fixed disk devices such as hard disks, flexible disks, optical disks, etc. can be used as the storage unit 106.

[0025] The storage unit 106 includes a product master 106a, a product group master 106b, a manufacturer master 106c, a sales restriction master 106d, and a data file 106e. Fig. 2 is a diagram showing an example of the configuration of the product master 106a. Fig. 3 is a diagram showing an example of the configuration of the product group master 106b. Fig. 4 is a diagram showing an example of the configuration of the manufacturer master 106c. Fig. 5 is a diagram showing an example of the configuration of the sales restriction master 106d.

[0026] The product master 106a can be configured as a table or the like in which product codes and manufacturer codes are registered in association with each other, as shown in FIG.

[0027] The product group master 106b can be configured as a table or the like in which product group codes and product codes are registered in association with each other, as shown in FIG.

[0028] The manufacturer master 106c can be configured as a table in which manufacturer codes are registered, as shown in FIG.

[0029] The sales restriction master 106d is a master for setting the product group or manufacturer for which sales are restricted for each customer. As shown in Fig. 5, the sales restriction master 106d can be configured as a table or the like in which customer codes, product group codes, manufacturer codes, and permission settings for whether sales are permitted are associated and registered. The permission settings are "0: warning", "1: error", "2: permitted", and "no setting". Depending on the setting value of the "permission setting" in the sales restriction master 106d, a warning or error message is displayed on the order entry screen.

[0030] For example, if the setting is "0: Warning", a warning message will be displayed stating "Restrictions against sales have been applied. Do you want to proceed with registration?". If the setting is "1: Error", an error message will be displayed stating "Registration is not possible as restrictions against sales have been applied." If the setting is "2: Allowed" or "Not set", no warning or error will be displayed and normal order entry will be possible.

[0031] The data file 106e is a file for storing various data such as order data, etc. The order data may include data such as an order number, a customer, a product, an order quantity, and an order amount.

[0032] Returning to Fig. 1, the control unit 102 is a CPU or the like that performs overall control of the sales restriction device 100. The control unit 102 has an internal memory for storing control programs such as an OS, programs that define various processing procedures, and required data, and executes various information processing based on these stored programs. In terms of functional concepts, the control unit 102 includes a master maintenance unit 102a, an order input unit 102b, an input restriction unit 102c, and a screen display control unit 102d.

[0033] The master maintenance unit 102a performs settings such as inputting, adding, and changing data for the product master 106a, the product group master 106b, the manufacturer master 106c, and the sales restriction master 106d, in response to, for example, the operator's operation of the input device 112 on a master maintenance screen (not shown) displayed on the monitor 114.

[0034] The order input unit 102b inputs order data in response to, for example, an operator's operation of the input device 112 on an order input screen (not shown) displayed on the monitor 114, and registers the data in the data file 106e.

[0035] When a customer and product are entered on the order entry screen, the input restriction unit 102c retrieves a product group or manufacturer from the sales restriction master 106d using the entered customer as a key, and restricts the order entry if the entered product is linked to a product group retrieved by reference to the product group master 106b, or if the entered product is linked to a manufacturer retrieved by reference to the product master 106a.

[0036] The input restriction unit 102c may restrict order input in accordance with the permission settings in the sales restriction master 106d.

[0037] The input restriction unit 102c may display a warning message on the order input screen when the permission setting in the sales restriction master 106d is a warning.

[0038] If there is an error in the permission setting of the sales restriction master 106d, the input restriction unit 102c may display an error message on the order entry screen and disallow order entry.

[0039] The input restriction unit 102c may temporarily permit order entry when the permission setting in the sales restriction master 106d is "permitted."

[0040] The screen display control unit 102d controls the display of various screens (for example, an order input screen, a master maintenance screen, etc.) displayed on the monitor 114 and the input therefor.

[0041] [3. Specific Examples] A specific example of the process of control unit 102 of sales restriction device 100 according to the present embodiment will be described with reference to FIGS.

[0042] (3-1. Master maintenance processing) 6 is a diagram showing examples of setting the product master 106a, the product group master 106b, the manufacturer master 106c, and the sales restriction master 106d. The master maintenance unit 102a executes a master maintenance process, and sets data in the product master 106a, the product group master 106b, the manufacturer master 106c, and the sales restriction master 106d in response to, for example, an operator's operation of the input device 112 on a master maintenance screen (not shown) displayed on the monitor 114.

[0043] In the example of product master 106a in FIG. 6, the first line has the product code "101-0011" and manufacturer code "M100", the second line has the product code "101-0012" and manufacturer code "M100", the third line has the product code "101-0013" and manufacturer code "M100", the fourth line has the product code "101-0014" and manufacturer code "M100", and the fifth line has the product code "101-0015" and manufacturer code "M200".

[0044] In the example of the product group master 106b, the first line has a product group code "A100" and a product code "101-0012", and the second line has a product group code "B100" and a product code "101-0013".

[0045] In the example of the manufacturer master 106c, "M100" is set in the first line, and "M200" is set in the second line.

[0046] In the example of sales restriction master 106d, the first line has customer code "10011," product group code "B100," manufacturer code "(not set)," and permission setting "0: warning," and the second line has customer code "20011," product group code "(not set)," manufacturer code "M200," and permission setting "1: error."

[0047] (3-2: Input restriction processing) Fig. 7 is a diagram for explaining the sequence and corresponding patterns of the input restriction process. Fig. 8 is a diagram showing an example of the processing flow of the input restriction process. In the following explanation, the master setting example of Fig. 6 is used for explanation. The input restriction unit 102c executes the input restriction process, and when a customer and a product are input on the order input screen, it acquires a product group or manufacturer from the sales restriction master 106d using the input customer as a key, and restricts the order input when the input product is linked to the product group acquired by referring to the product group master 106b, or when the input product is linked to the manufacturer acquired by referring to the product master 106a.

[0048] In FIG. 7, in STEP 1, if the product belongs to a product group code in the sales restriction master 106d, the permission setting is "0: warning" and the product is subject to a disapproval check. For example, if the value is "0: Warning", a warning message stating "Restrictions against sales have been applied. Do you want to register the product?" will be displayed on the order entry screen.

[0049] In STEP 2, if the manufacturer code in the sales restriction master 106d is included, the permission setting is "1: Error" and the product is subject to a disallowance check. In the case of "1: Error", an error message is displayed stating "Registration is not possible because sales disallowance restrictions have been applied." In the case of "1: Error", the order data cannot be registered, so the warning is stricter than "0: Warning", which allows the operator to register the order data at their discretion.

[0050] An explanation will be given for cases that do not fall under STEP 1 and 2. When the permission setting is "2: Allowed" or when the product group code and manufacturer code are not set, registration is possible without checking the order entry screen. The permission setting "2: Allowed" is for temporary permission, and can be used when you want to exclude a product from being checked depending on the timing. For example, if a certain product is to be allowed temporarily (seasonally), set "2: Allowed" and set "0: Warning" or "1: Error" at other times, rather than setting it to "No setting," it is easier for the operator to understand that the product is subject to seasonal sales restrictions (allowed), and this makes the setting easier.

[0051] Fig. 8 is a diagram showing the process flow of the input restriction process executed by the input restriction unit 102c. In Fig. 8, when a customer code and a product code are input on the order input screen (S1), it is determined whether or not there is a product group code linked to the input customer code in the sales restriction master 106d (S2). If there is no product group code linked to the customer code (S2 "No"), the process proceeds to S4.

[0052] On the other hand, if there is a product group code linked to the customer code (S2 "Yes"), it is determined whether the input product code is linked to that product group code in the product group master 106b (S3). If the input product code is not linked to that product group code in the product group master 106b (S3 "No"), the process proceeds to S4. On the other hand, if the input product code is linked to that product group code in the product group master 106b (S3 "Yes"), input restrictions are imposed on the corresponding permission settings in the sales restriction master 106d (S6).

[0053] In S4, it is determined whether or not there is a manufacturer code linked to the customer code entered in the sales restriction master 106d. If there is no manufacturer code linked to the entered customer code ("No" in S4), the process proceeds to S7. If there is a manufacturer code linked to the entered customer code ("Yes" in S4), it is determined whether or not the entered product code is linked to that manufacturer code in the product master 106a (S5).

[0054] If the input product code is not linked to the manufacturer code in the product master 106a (S5 "No"), the process proceeds to S7. On the other hand, if the input product code is linked to the manufacturer code in the product master 106a (S5 "Yes"), input restrictions are imposed on the corresponding permission settings in the sales restriction master 106d (step S6).

[0055] In S7, since no input restriction is implemented, order input (registration) is possible.

[0056] For example, if customer code "10011" and product code "101-0013" are entered, in FIG. 6, there is a product group code "B100" linked to customer code "10011" in the sales restriction master 106d ("Yes" in S2), and the entered product code "101-0013" is linked to the product group code "B100" in the product group master 106b ("Yes" in S3), so an input restriction of the corresponding permission setting "0: Warning" in the sales restriction master 106d is imposed (S6), and the message "A sales prohibition restriction has been applied. Do you want to proceed with registration?" is displayed on the order entry screen.

[0057] Also, if customer code "20011" and product code "101-0015" are entered, in FIG. 6, there is a manufacturer code "M200" linked to the customer code "20011" entered in the sales restriction master 106d ("Yes" in S3), and the entered product code "101-0013" is linked to the manufacturer code "M200" in the product master 106a ("Yes" in S4), so an input restriction is imposed with the corresponding permission setting "0: Error" in the sales restriction master 106d (S6), and the message "The manufacturer has imposed a sales prohibition restriction" is displayed on the order entry screen, and order entry (registration) is not permitted.

[0058] As described above, according to this embodiment, there are provided a product master 106a in which products are registered in association with manufacturers that produce the products, a product group master 106b in which products are registered in association with product groups that indicate the group of the products, a sales restriction master 106d in which product groups or manufacturers to which sales are restricted are registered in association with each other for each customer, and an input restriction unit 102c which, when a customer and product are input on the order input screen displayed on the monitor 114, retrieves a product group or manufacturer from the sales restriction master using the input customer as a key, and restricts order input when the input product is linked to a product group retrieved with reference to the product group master, or when the input product is linked to a manufacturer retrieved with reference to the product master. Therefore, it is possible to restrict sales for each customer when an order is input for a product, depending on the manufacturer that produced the product or the group of the product.

[0059] [4. Contribution to the United Nations-led Sustainable Development Goals (SDGs)] This embodiment can contribute to improving business efficiency and promoting appropriate management decisions by companies, thereby making it possible to contribute to goals 8 and 9 of the SDGs.
