Description

  The present invention relates to a computer system for realizing inter-company electronic commerce and a computer system program.

Until now, various electronic commerce methods, that is, EDI, have been introduced and widely used for mass transactions between large companies. On the other hand, for a small amount of business-to-business transactions, EDI capital investment has become large, so transactions using paper order forms and FAX order forms have continued for many years.
When the Internet spread in the latter half of the 1990s, inter-company Internet procurement by a procurement WEB site method established by a large ordering company using this has spread.
On the other hand, the introduction of inter-company Internet sales based on the sales WEB site method by the ordering company has not progressed, and the use of the sales WEB site that has already been introduced is not ridiculous. Many transactions using FAX order forms are used.
On the other hand, in recent years, Internet sales for general consumers are rapidly spreading, and further development is expected in the future.
The reason for this difference in Internet sales is due to the difference between general consumer transactions and inter-company transactions in transaction settlement, and there is no easy-to-use e-commerce system that is easy to use for inter-company transactions. .

  The reason why sales for general consumers are widespread is that the order to settlement is completed on the sales WEB site provided by the contracting company. When the general consumer accesses the sales WEB site of the contracting company, an electronic catalog for product search is displayed on the WEB screen. The selected product is put in the shopping cart, and the payment method is selected and specified on the payment screen. When the order button on the sales WEB screen is depressed, the order contract is established.

Since manufacturing equipment parts in the manufacturing industry have many items and complicated specifications, the person in charge of the ordering company checks the specifications and price of the product to be ordered by referring to the product catalog of paper materials distributed from the ordering company. Confirm the product number of the ordered product.
Next, the ordering company's procurement system screen is opened, and the product number determined in the product catalog is input to place an order. The procurement system issues an order form and sends the order form to the contracting company by mail or FAX. When the ordering company and the order receiving company are connected by EDI, order information is transmitted by EDI.

Since product selection and product specification determination based on such a product catalog are time-consuming and inefficient work for the person in charge of the ordering company, sales for business-to-business transactions by the contracting company are also used in business-to-business transactions to improve this work. WEB site has been provided.
Similar to the general consumer sales WEB site, this sales WEB site is provided with a sales system having a product search function using an electronic catalog and an order receiving function such as a shopping basket.

However, as described in the paragraph 0009, in the business-to-business transaction, the ordering operation is managed by the procurement system in the ordering company, and the formal order must be made from the in-house procurement system. Since inter-company transactions are conducted under these conditions, even if the contracting company establishes its own sales WEB site, orders placed on this site are linked to the procurement system in the ordering company of the orderer. Therefore, the ordering company cannot centrally manage orders via the sales WEB.
For this reason, many ordering companies do not accept orders from sales WEB sites of ordering companies other than orders for small office supplies.

  As a result, the sales WEB site of the ordering company uses only the electronic catalog, and the order function from the sales WEB site is hardly used.

  As a countermeasure, there is a sales WEB site that has a function to download order information from the sales WEB site of the ordering company. However, since the download data format is the data format of the ordering company, the ordering company procures this downloaded data in its own procurement. In order to import into the system, it is necessary to convert and import into the company's own format for each contracting company. For this reason, this function is hardly used.

  Even if you select a product in the electronic catalog, you must manually enter the order data into your procurement system, so there is not much difference between using the paper electronic catalog and using the electronic catalog on the sales website. Not.

The merit of conducting the inter-company transaction by the electronic data exchange method is that the data exchange between the ordering company and the order-receiving company can be executed without human intervention.
However, since the sales WEB system provided so far is a mechanism that requires many manual operations until the orderer completes the ordering work, it has only partially spread.

  In the future, in order to expand the use of the sales WEB site of the ordering company in the business-to-business transaction, it is required to provide means for data linking the sales WEB site of the ordering company and the procurement system of the ordering company.

  In order to solve the above problems, the sales application of the ordering company's sales WEB site and the procurement application of the ordering company can directly exchange data without human intervention.

  Order data entered by the person in charge of ordering at the ordering company accessing the sales WEB site of the ordering company is stored in the sales application of the sales WEB site of the ordering company. However, since this input data is not order data input to the procurement system of the ordering company, it is only provisional order data.

An object of the present invention is to provide an inter-company electronic commerce computer system and a computer system program for inputting the provisional order data to a procurement system of an ordering company without human intervention.
Specifically, the present invention provides the following.

The computer system characterized in that the EDI relay unit converts the received ordering company format temporary order EDI data into the ordering company format temporary order EDI data and transmits it to the ordering company distributed by the login ID; And programs for computer systems

  The present invention provides a new mechanism for connecting an ordering company's WEB sales site and an ordering company's procurement system in an inter-company EDI system. This provides both the ordering company and the contracting company with the benefits of digitizing transactions, enabling the spread of WEB sales sites for intercompany transactions that are not widespread, and the Japanese industry through digitalization of the entire value chain of Japanese industries. The effect which contributes to productivity improvement of can be acquired.

  An example of a preferred embodiment according to the present invention will be described below based on the drawings.

[System overall configuration]
FIG. 1 is a block diagram showing the overall configuration of a computer system 1 that executes a program according to an example of a preferred embodiment of the present invention.

The computer system is configured on a network that connects an ordering enterprise group 10 including one or a plurality of ordering enterprises 10a, 10b and the sales enterprise 20a, and the ordering enterprise 10a and the like are each a personal computer 11a equipped with a browser and an EDI connection terminal. The sales company 20a includes a sales WEB site 21a, an EDI connection terminal 22a, and an EDI conversion function 23a.
The personal computer 11a of the ordering company group 10 is connected to the sales WEB site 21a of the sales company 20a via the Internet.
The EDI connection terminal 12a of the ordering company group 10 is connected to the EDI connection terminal 22a of the sales company 20a through an EDI line.

FIG. 2 is a data flow and EDI document flow diagram according to an example of the preferred embodiment of the present invention shown in FIG.
Hereinafter, an example of the embodiment of the operation of the system according to the present invention will be described.

  With reference to FIG. The orderer of the ordering company 10a logs in to the sales WEB site 21a of the sales company 20a from the browser installed in the personal computer 11a with the ordering company ID, and inputs the provisional order data 100a of the product to be ordered from the browser display screen of the sales WEB site 21a. To do. Data input as the temporary order data 100a includes, for example, a product name, a temporary order quantity, a desired delivery date, and the like.

  The order receiving company 20 registers in advance the conditions for converting the temporary order data 100a into the EDI format required by the ordering company 10a in the conversion condition registration function 24a.

The operation of the conversion condition registration function 24a will be described with reference to FIGS. 2 and 5, for example, when the format of the temporary order information EDI document 200a requested by the ordering company 10a is CSV.
The provisional order information EDI document 200a to be transmitted to the ordering company 10a includes data specifying the provisional order such as the product name, provisional order quantity, desired delivery date, orderer ID, sales company ID, and provisional order number issued by the sales company. Must be added. The data arrangement order designation table 2000a displayed on the user interface screen of the conversion condition registration function 24a includes a data item sequence 2001a and a data arrangement order designation column 2002a. The conversion condition registration function 24a can be registered by inputting the CSV data arrangement order designated by the ordering company 10a into the data arrangement order designation column 2002a.
For the ordering company 10b as well, the CSV data arrangement order designated in the data arrangement order designation table 2000b can be similarly input, and different conversion conditions can be registered for each ordering company.

Since the format of the order information EDI document 300a received by the sales company 20a from the ordering company 10a is transmitted in a format unique to the ordering company 10a, data cannot be taken into the sales function 28a as it is, and conversion is necessary. The case where the transmission document is CSV will be described with reference to FIGS.
The data array order specification table 3000a displayed on the user interface screen of the conversion condition registration function 24a for converting the order information EDI document 300a includes a data item column 3001a and a data array order specification column 3002a. The conversion condition registration function 24a can be registered by inputting the CSV data arrangement order designated by the sales company 20a into the data arrangement order designation column 3002a.
For the ordering company 10b as well, the CSV data array order to be specified in the data array order specification table 3000b can be similarly input, and different conversion conditions can be registered for each ordering company.

  The EDI conversion function 23a converts the provisional order data input to the sales WEB site with the conversion conditions registered in the conversion condition registration function 24a, organizes it into the provisional order information EDI document 200a, and the EDI transmission function 25a of the EDI connection terminal 22a. Hand over to

  The EDI transmission function 25a transmits the delivered provisional order information EDI document 200a to the ordering company 10a via the EDI line.

  Since a large ordering company has already connected the companies with an EDI line, an EDI document in the designated EDI data format can be received as it is without changing the existing equipment.

  The ordering company 10a receives the provisional order information EDI document 200a by the EDI receiving function 13a of the EDI connection terminal 12a, and takes it into the purchasing function 14a without human intervention.

  The ordering company 10a imports the received provisional order information EDI document 200a into the purchasing function 14a, thereby completing the regular purchasing procedure. Thereafter, the order information EDI document 300a in its own data format is delivered to the EDI transmission function 15a and transmitted via the EDI line.

  The sales company 20a receives the order information EDI document 300a by the EDI receiving function 26a, converts the data into a data format required by its sales function 28a by the EDI data conversion function 27a, and takes the order information EDI document 300a into the sales function 28a. Thus, a sales contract between the ordering company 10a and the sales company 20a is formally established.

In the present invention, the provisional order information EDI document 200a is converted in advance into a data format that can be received by the EDI connection terminal 12a of the ordering company 10a, so that the ordering company 10a does not need to provide a special conversion function. Further, when the regular order information EDI document 300a is transmitted, it can be transmitted through the existing EDI line, and the sales company 20a performs data conversion necessary for data import into the sales function 28a of the company, so that the ordering company 10a has special data. Does not require conversion function.
In this way, if the present invention is used, the ordering company 10a does not require a large investment, and it becomes possible to cooperate with its own purchasing function 14a while using the sales WEB site 21a of the sales company 20a. The use of the WEB site becomes widespread, and EDI conversion of business-to-business transactions can be promoted.

In the present invention, the use of the sales WEB site is promoted for the sales company, thereby obtaining a great merit that digitization of the order data is realized. However, to realize this merit, the following investments are required.
In other words, in order for a plurality of ordering companies to easily incorporate the provisional order information EDI document into their own purchasing function, the selling company 20a requires different conversion order registration functions 24a individually required by the plurality of business partner ordering companies. It is necessary to have a function for registering and converting conversion conditions for conversion to the EDI data format in advance.
In addition, in order to import the order information EDI document in various data formats transmitted from a plurality of supplier ordering companies into the sales function of the sales company, individual conversion conditions for each ordering company are registered in the conversion condition registration function 24a. There must be.
In order to realize these registration functions and conversion functions, a certain amount of investment is required.

  On the other hand, for the ordering company 10a, there is a problem that it takes time and effort because the EDI document conversion condition requested by the company must be performed for each supplier sales company when dealing with a plurality of sales companies.

  For solving the problems shown in the above paragraphs 0038 and 0039, another example of a preferred embodiment according to the present invention will be described below with reference to the drawings.
