[0042] Subsequently, the unit price management device 100 causes the display control unit 102e to display on the monitor 114 a unit price difference inquiry screen for each product code in which a difference occurs between the order unit price based on the order data and the purchase unit price, and the update unit 102f executes a unit price difference inquiry process for updating the purchase unit price in the product unit price master 106a by supplier according to the operation content of the user to the input device 112 (step S8).

[0043] FIG. 10 is a diagram showing an example of an order data table in order data. FIG. 11 is a diagram showing an example of a unit price difference inquiry screen.

[0044] In the order data table T7 shown in FIG. 11, it is stored for each product code (record) in which a difference occurs between the purchase unit price and the order unit price. In this case, as shown in FIG. 11, the display control unit 102e displays a unit price difference inquiry screen P1 including a product code selection table Q1 in which a plurality of product codes in which a difference occurs between the order unit price and the purchase unit price based on the order data table T7 can be selected.

[0045] The unit price difference inquiry screen P1 includes order date cells K1 and K2 where the order date can be input, order number cells K3 and K4 where the order number can be input, and a supplier code cell K5 where the supplier code can be input. Further, the unit price difference inquiry screen P1 includes a product code selection table Q1 where the user can select a desired product code from product codes with a difference between the purchase unit price and the order unit price at the time of order, and an update button B1 that can accept the input of an instruction signal to update the order unit price of the selected product code to the purchase unit price.

[0046] In the case shown in FIG. 11, the display control unit 102e may extract product codes corresponding to order data that match the extraction information input from the storage unit 106 based on the extraction information input to each of the order date cells K1 and K2, the order number cells K3 and K4, and the supplier code cell K5, and that have a difference between the purchase unit price and the order unit price at the time of order, and display them on the unit price difference inquiry screen P1. At this time, even when the information input to each of the order number cells K3 and K4 and the supplier code cell K5 matches, the display control unit 102e excludes product codes in which the update flag in the order data stores "1" from the target for the unit price difference inquiry screen P1.

[0047] When the user selects a product code with a difference between the purchase unit price and the order unit price at the time of order via the input device 112 and presses the update button B1, the update unit 102f updates the order unit price of the selected product code to the purchase unit price.

[0048] FIG. 12 is a diagram showing an example of a product table for the product code selected by the user.

[0049] As shown in FIGS. 12 to 14, the update unit 102f updates the ordering unit price of the selected product code to the purchase unit price, and updates the purchase unit price in the product unit price master 106a by supplier from "150" to "160". Further, the update unit 102f updates the update flag indicating that the purchase unit price in the order data table T12 has been updated to "1". As a result, even if there is a difference between the ordering unit price at the time of placing an order for the product with the manufacturer and the purchase unit price based on the incoming unit price of the product when the manufacturer ships the product, the ordering unit price can be updated to the purchase unit price based on the incoming unit price of the product when the manufacturer ships the product, so that it is possible to prevent an arithmetic error from occurring at the time of payment.

[0050] Returning to FIG. 3, the description after step S9 will be continued. In step S9, the unit price management device 100 performs a payment input process for accepting a payment input corresponding to an order according to the operation content input by the user via the input device 112. After step S9, this process ends.

[0051] According to the embodiment described above, when there is a difference between the ordering unit price based on the order data and the purchase unit price, since the update unit 102f updates the purchase unit price in the product unit price master 106a by supplier to the purchase unit price associated with the incoming unit price, even if there is a difference between the ordering unit price at the time of placing an order for the product with the manufacturer and the purchase unit price based on the incoming unit price of the product when the manufacturer ships the product, the ordering unit price can be updated to the purchase unit price based on the incoming unit price of the product when the manufacturer ships the product, so that it is possible to prevent an arithmetic error from occurring at the time of payment.

[0052] Also, according to the embodiment, since the update unit 102f updates the update flag indicating that the purchase unit price in the order data table T12 has been updated to "1", it can be managed separately from other unupdated product codes.

[0053] Further, according to the embodiment, since the display control unit 102e displays the product codes with a difference between the ordering unit price based on the ordering data and the purchase unit price on the monitor 114, the user can intuitively grasp the product codes with a difference between the ordering unit price and the purchase unit price.

[0054] Further, according to the embodiment, since the update unit 102f updates the ordering unit price of the selected product code to the purchase unit price and updates the purchase unit price in the purchase unit price master 106a by supplier, the user can update while confirming the difference between the ordering unit price and the purchase unit price. Therefore, it is possible to reduce the time required for confirming the cause of the variance and the variance adjustment work before the end of each month.

[0055] [3.
