## Title
System and method for synchronizing ledger accounts by company group

## Abstract

A system and method for keeping ledger accounts in synchronization between a back-end procurement system and a front-end requisition and catalog system. An extract utility extracts a file of general ledger (G/L) accounts, including account code, description, and company code, from a chart of accounts in the back-end and transfers it to the front-end, where it is updated by an update utility to include company group code from a company group table and then loaded into a data store of valid general ledger accounts. Maintenance of the front end data store of valid accounts includes pushing to all companies in a company group ledger code entered with respect to any one of the companies in that group.

BACKGROUND OF THE INVENTION
1. Technical Field of the Invention
This invention pertains to accounting and procurement systems. More particularly, it relates to synchronizing ledger accounts by company group between a front-end requisition and catalog system and a back-end accounting and procurement system.
2. Background Art
There is a need in the art for a system and method for keeping ledger accounts in synchronization between a back-end procurement system and a front-end requisition and catalog system.
In such a system, the same general ledger accounts must exist in each system. This is typically solved by daily bridging of accounts from the back-end procurement system to the front-end requisition and catalog system.
However, maintaining such synchronization when implemented for many different customer companies by an enterprise providing procurement services to these customer companies is complex and time consuming, often involving manual updating of a vast number of commodity documents describing the commodities available to customers entering requisitions. There is, therefore, a need for a much simplified and automatic synchronization process.
It is an object of the invention to provide an improved system and method for synchronizing ledger accounts between a back-end procurement system and a front-end requisition and catalog system.
It is a further object of the invention to provide a system and method for synchronizing such ledger accounts in an enterprise on behalf of a large number of customer companies.
SUMMARY OF THE INVENTION
A system and method for keeping ledger accounts in synchronization between a back-end procurement system and a front-end requisition and catalog system. An extract utility extracts a file of general ledger (G/L) accounts, including account code, description, and company code, from a chart of accounts in the back-end and transfers it to the front-end, where it is updated by an update utility to include company group code from a company group table and then loaded into a data store of valid general ledger accounts. Maintenance of the front end data store of valid accounts includes pushing to all companies in a company group code entered with respect to one of the companies in that group.
In accordance with an aspect of the invention, there is provided a computer program product configured to be operable for maintaining ledger accounts in synchronization between a back-end procurement system and a front-end requisition and catalog system where they are associated by company group code.
Other features an d advantages of this invention will become apparent from the following detailed description of the presently preferred embodiment of the invention, taken in conjunction with the accompanying drawings.



BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a high level system diagram illustrating an enterprise system for providing procurement services with respect to a plurality of vendors on behalf of a plurality of company groups of related customer companies in accordance with the preferred embodiment of the invention.
FIG. 2 is a diagram illustrating the extract and update utilities of the preferred embodiment of the invention for synchronizing the chart of accounts by company group code across front-end and back-end systems.
FIG. 3 is a diagram illustrating the generation of a data store of valid accounts.
FIG. 4 is a diagram illustrating the generation of a drop down list of account code/description data.



BEST MODE FOR CARRYING OUT THE INVENTION
Referring to FIG. 1, the procurement services organization of an enterprise 244 provides procurement services to a plurality of companies 248, 249 organized in a plurality of company groups 241-243 with respect to a plurality of vendors 245-247.
Referring to FIGS. 2 and 3, in accordance with a preferred embodiment of the invention, a system and method is provided for keeping ledger accounts in synchronization between a back-end procurement system 42, a procurement system, such as SAP, and a front-end requisition and catalog system 40, such as the IBM requisition and catalog system referred to as Req/Cat Web. Company grouping codes are applied to general ledger accounts (GL) bridged from SAP to Req/Cat Web (RCW).
In an exemplary embodiment of the invention, an enterprise resource planning system 42, known as SAP, is used as the procurement engine and accounts payable system for an enterprise, such as IBM, which provides procurement services for a plurality of customer companies 248.
REQ/CAT Web (RCW) 40 is a requisition system implemented on a company intranet.
In accordance with the preferred embodiment of the invention a bridge generally comprising an extract utility 258 and an update utility 250 is provided to extract a file of general ledger (G/L) accounts 49, including account code 260, description 262, and company code 248, from a chart of accounts 252 in SAP 42 and transfer it to RCW 40, where it is updated by utility 250 to associate company group code 253 from company group table 251 and then loaded into a data store 254 of valid general ledger accounts. This association of company group code 253 to company 248 may be by physically including field 253 in the data store 254 record, or logically by referencing company group table 251 by company code 248 to obtain company group code 253.
Referring to FIG. 3, the bridge and store are maintained at a company level.
The chart of accounts (also referred to as the general ledger) is combined by company groups in data store 254 for means of access and data integrity.
Referring to FIG. 4, a procurement administrator interfaces with RCW 40 to provide for each company commodity code a company commodity document describing in detail the commodity. This commodity document is used in association with a company group association table 272 to generate a drop down list 280 of valid accounts for use by a customer requester in preparing a requisition. Associated with each commodity code 268 are one or more purchasing types, such as expense, capital, external (resale), unallowable and allowable buys. Company group association table 272 is provided for associating commodity codes 268 with general ledger account codes 276 from data store 254. Those account codes 276 corresponding to commodity codes 268 for buy type 270 and company group 242 from table 251 for the company 249 of this customer requestor are presented in drop down list 280 as account codes 278 and description 282.
When updating the company group association table, the addition or change of a commodity code 274/account code 276 association entered on behalf a company 249 is pushed to all other companies 248 in the company group 242.
Advantages over the Prior Art
It is an advantage of the invention that there is provided an improved system and method for synchronizing ledger accounts between a back-end procurement system and a front-end requisition and catalog system.
It is a further advantage of the invention that there is provided a system and method for synchronizing such ledger accounts in an enterprise on behalf of a large number of customer companies.
