The merchandise delivery company terminals 21 to 2N are each configured by an information processing device such as a personal computer.

  The product master registration management server 10 is a server managed by a system administrator of the product master registration system 100, for example, and manages a website (product master registration site) for registering product information in the product master of each retail store. And so on.

  The product master registration management server 10 includes a product master registration related DB 11 that stores various information necessary for registering product information in the product master of each retail store, such as a product master registration format of each retail store. Yes. The product master registration related DB 11 may be inside or outside the product master registration management server 10.

  The merchandise delivery company terminals 21 to 2N are information processing apparatuses managed by a merchant (a merchandise delivery company: a merchandise manufacturer, a wholesale company, a buyer, etc.) that delivers merchandise to a retail store. In this example, it is assumed that the product delivery company is responsible for registering product information in the product master.

  The retail store servers 31 to 3N are installed, for example, in the retail chains A to N, respectively, and are managed by, for example, a retail chain manager who manages the retail chains A to N. Although not shown in the retail store servers 31 to 3N, a POS register used in each retail chain A to N (a register installed at a purchase amount payment place, for example, for a POS system attached to a product) Various functions such as reading a bar code (an example of a POS code: hereinafter referred to as a POS bar code) and printing purchase contents on a receipt using a product name and a product price specified based on the POS bar code Or a computer that performs POS data intra processing before the processing of the retail store servers 31 to 3N.

  FIG. 2 is an explanatory diagram showing an example of a product master registration format defined by the retail chain A (store A). The merchandise master registration format of each retail chain is registered in the merchandise master registration related DB 11. As shown in FIG. 2, the product master registration format is provided with an item display field in which items to be registered are shown and a content input field for inputting (filling in and describing) the contents of each item. .

  The items to be registered include, for example, the product name of the product, the product standard (container size, weight), the number of the product, the delivery conditions (price, lead time) of the product, the product description of the product A JAN (Japanese Article Number) or EAN (European Article Number) code commonly used as an identification code for the product, a manufacturing code assigned by the manufacturer, and the like are conceivable.

  Since the items to be registered are determined for each retail chain, the type and number of items to be registered are different for each retail chain.

  FIG. 3 is an explanatory diagram showing an example of the item identification code registration table. The item identification code registration table is a table in which an item identification code uniquely assigned to each item listed in the product master registration format of each retail chain is registered, and is registered in the product master registration related DB 11. Shall.

  In the item identification code registration table, each item listed in the merchandise master registration format of each retail chain, the corresponding retail chain (retail store) name, and the item identification code are registered in association with each other. The item identification code is a code uniquely given to each item listed in the merchandise master registration format of each retail chain, and is, for example, a court given by the merchandise master registration management server 10. By using the item identification code, it is possible to specify which item in the merchandise master registration format of which retail chain.

  FIG. 4 is an explanatory diagram showing an example of the item identification code type correspondence table. The item identification code type correspondence table is a table in which the item type and the item identification code corresponding to the item are associated with each item type listed in the merchandise master registration format of each retail chain. Suppose that it is registered in the product master registration related DB 11.

  In this example, the type of an item that may be the same content in each retail chain is “type A”, and the type of an item that is not necessarily the same content in each retail chain but may be the same content is “type B”. In each retail chain, the type of an item that is different from the same content and not the same content is “Category C”. As the item of “type A”, for example, there are items having the same contents in each retail chain such as a product name and a JAN code. As the item of “type B”, there are items that have the same contents in each retail chain such as product descriptions and standards. As the item of “Category C”, there are items that need to be determined separately for each retail chain, such as the number of entries and delivery conditions.

  The item identification code type correspondence table includes items listed in the merchandise master registration format of each retail chain, the type of the item, and each item identification code indicating the item in the merchandise master registration format of each retail chain. Registered in association.

Next, the operation of the product master registration system 100 of this example will be described.
FIG. 5 is a flowchart showing an example of the product master comprehensive registration process executed by the product master registration management server 10 in the product master registration system 100 of this example. The product master comprehensive registration process is executed in response to a request from the product delivery company terminals 21 to 2N. Here, a case where the product master comprehensive registration process is executed in response to the product master comprehensive registration request from the product delivery company terminal 21 operated by the product master registration person X of the product delivery company A will be described as an example.

  In the product master comprehensive registration process, first, the product master registration management server 10 receives a product master registration format to be registered from the product delivery company terminal 21 (step S101). Specifically, selection of a retail chain (store) to be registered is accepted.

  When there is an access from the product delivery company terminal 21, the product master registration management server 10 transmits a product master registration store selection screen to the product delivery company terminal 21. In the product master registration attachment selection screen, for example, as shown in FIG. 6, an input area 101 for inputting the company code of the product delivery company A, a store selection area 102 for selecting a store to be registered in the product master, A selection completion button 103 that is pressed when selection is completed is provided. In this example, it is assumed that store A and store C are selected as shown in FIG. When the selection completion button 103 is pressed after the selection of the store is completed, the merchandise delivery company terminal 21 transmits registration target store information indicating the selected store to the merchandise master registration management server 10.

  When the registration target store information is received, the product master registration management server 10 accepts the product master registration format of each store A, C indicated by the registration target store information as the product master registration format to be registered.

  Next, the product master registration management server 10 reads the product master registration format (see FIG. 2) to be registered from the product master registration related DB 11, and item-identifies the item identification code of each item of the read product master registration format. Referring to the code registration table (see FIG. 3), the virtual format is generated by integrating all the product master registration formats to be registered with reference to the item identification code type correspondence table (see FIG. 4) (step S102). ).

  That is, the product master registration management server 10 refers to the item identification code type correspondence table and includes items to which at least one of the item identification codes of each item of each product master registration format to be registered belongs. A virtual format in which the type can be identified is generated.

  Next, the product master registration management server 10 transmits a product master registration screen including a product master comprehensive input area indicated by the generated virtual format to the product delivery company terminal 21 (step S103). The merchandise delivery company terminal 21 displays the received merchandise master registration screen on its own display device.

  In this product master registration screen, for example, as shown in FIG. 7, the product master comprehensive input area 201 and each store product master display area for displaying the input contents of the product masters of the stores A and C to be registered. 202, an individual input button 203 that is pressed when shifting to individual input, and an input completion button 204 that is pressed when the input is completed.

  The product master comprehensive input area 201 is an input area for product master comprehensive input indicated by the virtual format, and includes an item display area for displaying input items generalized for the items of type A and type B, and the type of each input item Are displayed, and an input area for inputting the contents of each input item is provided. In this example, in the type display area, the types A to C and the corresponding stores in the case of the type C are displayed. When the item content is described (input) in the input area of the commodity master comprehensive input area 201, the commodity delivery company terminal 21 transmits the input information to the commodity master registration management server 10.

  In each store product master display area 202, the input contents to the product master of each store A and store C to be registered are displayed for each store. The display content of each store product master display area 202 is appropriately updated according to the input status to the input area in the product master comprehensive input area 201.

  Next, the product master registration management server 10 determines whether or not the input information to the input area of the product master comprehensive input area 201 has been received from the product delivery company terminal 21 (step S104). Whether or not an individual input request from the company terminal 21 has been received (step S107) and whether or not an input completion notification has been received from the product delivery company terminal 21 by pressing the input completion button 204 is entered (step S114).

  When the input information is received from the merchandise delivery company terminal 21 (Y in step S104), the merchandise master registration management server 10 indicates the input information received in the input area of the corresponding item in the virtual format and each merchandise master registration format. The input content is reflected (step S105). That is, in this example, the input content indicated by the received input information is reflected in the input area of the corresponding item in the virtual format and the input area of the corresponding item in the merchandise master registration format of each store A and C.

  Then, the product master registration management server 10 transmits the reflected virtual format and product master registration format to the product delivery company terminal 21 (step S106). Upon receiving the reflected virtual format and product master registration format, the product delivery company terminal 21 displays the input contents of the virtual product master indicated by the virtual format in the product master comprehensive input area 201 and the product master registration format indicates The input contents of the product master of each store A and C are displayed in each store product master display area 202.

  For example, when “Tsubaki Onigiri” is input in the “Product Name” field on the screen shown in FIG. 7, the input contents are reflected by the processing of Steps S104 to S106, for example, as shown in FIG. Product master registration screen including a product master comprehensive input area 201 in which the virtual product master is displayed and each store product master display area 202 in which the product masters of the stores A and C reflecting the input contents are displayed. Is displayed on the merchandise delivery company terminal 21.

  Thereafter, for example, on the screen shown in FIG. 8, “100 pieces / day” is input to the item content of the type “type C (store A)” in the item “number of pieces”, and the type “ When “50 items / day” is input to the item content of “type C (store C)”, the virtual content in which the input content is reflected by the processing of step S104 to step S106, for example, as shown in FIG. A merchandise master registration screen including a merchandise master comprehensive input area 201 in which the merchandise master is displayed and each store merchandise master display area 202 in which the merchandise masters of the stores A and C reflecting the input contents are displayed It will be displayed on the supplier company terminal 21.

  When receiving an individual input request by pressing the individual input button 203 from the product delivery company terminal 21 (Y in step S107), the product master registration management server 10 sets an individual product master input area corresponding to the individual input request. The merchandise delivery company terminal 21 is instructed to perform main display (step S108). This instruction may be a main display instruction for the product master input area of an arbitrary store, and if the information indicating which store is included in the individual input request, the product master input area of the store The main display instruction may be used.

  When the merchandise delivery company terminal 21 receives the main display instruction, the merchandise delivery company terminal 21 displays a merchandise master registration screen on which the merchandise master input area of the store designated by the instruction is displayed. FIG. 10 is an explanatory diagram illustrating an example of a product master registration screen on which the product master input area of the store A is main displayed. The product master registration screen shown in FIG. 10 includes a product master input region 301 in which a product master input region of a certain store is mainly displayed, and a comprehensive input button 302 for returning to the product master comprehensive input screen for comprehensive input. Is provided. Note that, among the items shown in FIG. 10, the item content of the type A item (for example, product name) cannot be input, rewritten, or deleted in the product master input area 301. . That is, the product master registration management server 10 does not accept input information indicating the input content of the item content of the type A item (for example, product name) in the product master input area 301.

  When the product master registration screen displaying the product master input area of the store A is displayed, when the input information indicating the input content of the item content is received (Y in step S109), the product master registration management server 10 The input content indicated by the input information is reflected in the input area of the corresponding item in the product master registration format of the target store A (step S110).

  Then, the product master registration management server 10 transmits the reflected product master registration format to the product delivery company terminal 21 (step S111). When the product delivery company terminal 21 receives the product master registration format after reflection, the product delivery company terminal 21 displays the input contents of the product master of the store A indicated by the product master registration format in the product master input area 301.

  When a comprehensive input request is received by pressing the comprehensive input button 302 while the product master registration screen displaying the product master input area of the store A is displayed (Y in step S112), the product master registration management server 10 Transmits a main display instruction for main display of the product master comprehensive input area 201 reflecting the input contents so far to the product delivery company terminal 21 (step S113). The merchandise delivery company terminal 21 returns to the display of the merchandise master registration screen (see FIG. 9 and the like) on which the merchandise master comprehensive input area 201 is main displayed. In the product master registration screen, all input contents so far are reflected.

  As described above, the item contents are comprehensively input in the product master comprehensive input area 201, or the item contents are individually input in the product master input area 301. The contents are entered.

  Upon receiving an input completion notification by pressing the input completion button 204, the product master registration management server 10 ends the product master comprehensive registration process here. Note that each time the product master registration management server 10 receives input information, the product master registration management server 10 updates and stores the virtual product master indicated by the target virtual format and the product master of each store to be registered. Upon receipt of the input completion notification, the product master registration management server 10 stores the stored virtual product master being created and the product master of each store in the product master registration related DB 11 as the item contents are confirmed. .

  FIG. 11 is a flowchart showing an example of product master information registration processing executed by the product master registration management server 10 in the product master registration system 100 of this example. The product master information registration process is executed after the above-described product master comprehensive registration process (see FIG. 5) is completed. Here, a case where the virtual product master generated by the product master comprehensive registration process in response to the product master comprehensive registration request from the product delivery company terminal 21 and the product master of the stores A and C will be described as an example.

  In the product master information registration process, first, the product master registration management server 10 assigns a virtual product master code that can uniquely identify the virtual product master to the virtual product master generated in the product master comprehensive registration process ( Step S201).

  Next, the product master registration management server 10 assigns a product master code that can uniquely identify the product master to each of the product masters of the stores A and C generated by the product master comprehensive registration process (step S202). .

  Next, the merchandise master registration management server 10 uses the virtual merchandise master code (eg, “TSM00012345”) given in step S201 and the merchandise master codes given in step S202 (eg, “SMA0001234” and “SMC0003219”). ) And are stored in a product master code correspondence table as shown in FIG. 12, for example (step S203).

  Next, the product master registration management server 10 includes comprehensive product master information in which the virtual product master code assigned in step S201 is associated with the virtual product master generated in the product master comprehensive registration process, and the product master comprehensive registration process. The product master information associated with each product master code assigned in step S202 is stored in the product master registration related DB 11 (step S204).

  Then, the product master registration management server 10 transmits the product master information about each store to the retail store server managed by each store (step S205). Specifically, the product master information about the store A is transmitted to the retail store server 31 managed by the store A, and the product master information about the store C is transmitted to the retail store server 33 managed by the store C.

  As described above, in the above-described embodiment, the product master registration management server (product master comprehensive generation server) 10 receives a plurality of retail chains to be generated by the product master (step S101) and receives them. A virtual product for generating a virtual format (virtual product master) including all items of each product master defined by each of a plurality of retail chains (step S102), and inputting item contents of each item of the virtual product master A master input screen (see FIG. 7 and the like) is transmitted (step S103), the item content input on the virtual product master input screen is received (step S104), and the received item content is reflected in the corresponding item of each product master. Each product master is generated by (Step S105). Can be easily performed a registration operation of the product information to the product master in accordance with the reference format determined for each, it is possible to reduce the labor of the registration operator.

  In other words, according to a virtual format that includes all items of each product master defined by each of the plurality of retail chains, it is possible to input the item content of each product master together, and the item content of each product master can be input separately. Since the registration work becomes easier compared with the case of inputting, the labor of the registration worker can be reduced.

  In the above-described embodiment, the merchandise master registration management server 10 sets each item of the first type (type A) having the same item content in each retail chain among all items of each merchandise master.
