BACKGROUND OF THE INVENTION
1. Technical Field of the Invention
This invention pertains to a requisition and catalog system. More particularly, it relates to a leveraged procurement network (LPN) system for leveraging purchasing across company and company groups.
2. Background Art
Previously, an enterprise company provided procurement services to a customer company. The back end system for supporting these procurement services is bridged to a front end requisition and catalog system (Req/Cat Web, or RCW server) with which users from the customer company would interface to view a catalog of commodities and/or services and enter requisition requests.
When the enterprise company provides such procurement services to more than one customer company, it has heretofore been required to rewrite the front end system to accommodate the accounting rules required to support the procurement activities of each additional company. This is time consuming and complex. There is, therefore, a need in the art to provide a system and method whereby an enterprise may provide procurement services to a plurality of customer companies using the same front end requisition and catalog system for them all.
However, the data and accounting for one customer company must be isolated from viewing or use by other customer companies.
The Internet provides exchange mechanisms where suppliers bring goods and services to be offered and malls for shoppers to obtain them. These exchange mechanisms are largely independent with a single company selling and an individual from another company shopping. Generally, if companies wish to partner to gain advantage either from consolidating purchase volumes to obtain better prices or from creating a complete palette of business goods and services to establish a ‘one stop shop’, many individual relations are established and managed independently. Manual integration of systems to ensure members rights and responsibilities are met increase the bureaucracy and paperwork. Should a company endeavor to participate or host multiple trading networks, the membership management becomes very difficult.
There is, therefore, a need in the art for a system and method whereby an enterprise may leverage purchases by a plurality of customer companies for which it is providing procurement services against a common contract having volume specific terms and conditions.
It is an object of the invention to provide an improved system and method for procuring goods and services on behalf of customer companies.
It is a further object of the invention to provide a system and method for leveraging purchases of goods and services against the same volume specific contract by a plurality of unrelated customer companies.
It is a further object of the invention to provide a system and method for providing procurement services to a plurality of companies organized according to groups of related companies sharing access to selected resources across company groups and access to other resources only within company groups.
It is a further object of the invention to provide a system and method for leveraging purchasing across company groups while isolating information to individual company groups.
SUMMARY OF THE INVENTION

The operation and inter relationships of elements of the architecture of FIGS. 2–6 pertinent to the present invention will be described hereafter in connection with preferred and exemplary embodiments of the systems and methods of the invention.
In accordance with the preferred embodiments of the invention, a front end order system, such as a procurement catalog and requisition system 40, is rendered enabled to accommodate multiple businesses 248, 249 with complex accounting rules while providing secure information viewing in support of those businesses and their processes. Companies having common ownership, and therefore similar accounting systems, are grouped in procurement coalitions 242 for volume discounts and access to shared contracts. Procurement contracts may also be leveraged across company groups 243, 242.
Both leveraging access and maintaining isolation of data is done by identifying a user at log on as associated with a company group. That association then dictates what the user can see and do.
With respect to catalogs, for example, a vendor sends his catalog in across the firewall to the EDI electronic data interchange. The RCW application loads it into the catalog. Users can come in to RCW, authorized by their user profile, from several company groups using common catalog—none knowing that the other uses it or has access to knowledge of requisitions applied against its line items. SAP assembles requisitions from all these users, and cuts purchase orders periodically for those requisitions from the same company group. By identifying those requisitions to a particular contract, volume specific terms and conditions, for example, are leverage on behalf of the companies and company groups. Catalogs are, in the preferred embodiment, controlled at the company level because this allows easier support of regional catalogs.
With respect to accounting, by driving accounting by company group, a user in one company within the company group may, for example, charge purchase to a user account in another company within the same company group.
Referring to FIG. 7, the system of the preferred embodiment of the invention includes a plurality of companies 450–452 which are associated in company groups 242 and 243, requisition and catalog system 40, and procurement services system (SAP) 42. Associated with this system is a data interchange system 44, one of several possible communication paths with a plurality of vendors 246, 247. A company group may include one or more companies. Data interchange system 44 includes mail boxes 455, 456.
Users 450–452 are persons authorized by their respective companies to access requisition and catalog system 40. Requisition and catalog system 40 includes a user profile table 384 and a plurality of resources, shown here as catalogs 465, 476 and contract 469. Other examples of such resources include cost centers (that is, departments that can be charged), general ledger (G/L) account codes (that is, chart of accounts (COA)), user profile table 384 entries, business rules and defaults (such as those affiliated with accounting, specifying the fields that must be completed, for example, in creating a requisition and default data to be entered in those fields). All of these are generically referred to as procurement resources, and include process requirements and data resources accessible only to those users identified in their profiles as members of a particular company and, therefore, company group. (A company code will have a company group code associated with it.)
Referring to FIG. 9, user profile 384 includes, for each user, company group code, company code, plant code (that is, ship to location), employee serial number, E-mail address, and much more (not pertinent to the present invention.)
Referring to FIG. 8, an exemplary system for creating and maintaining user profile table 384 is shown. A plurality of related companies 59, 59A are connected to a hub server which includes a company group human resources file. Hub server is connected through fire wall 372 to a requisition and catalog (ReqCatWeb, or RCW) application server 376. RCW server 374 includes a company group HR file, a staging table build application 378 and a new employee profile build application 382 for building employee profile table 384. Applications 402, 404 are logically connected to database server 388, which includes staging table 380, user profile table 384, and plant code table 386.
Connected to an RCW web server 390 deployed to customer companies through extra net 394 is a browser operable by a user for accessing a catalog (not shown) maintained by the enterprise, and for submitting to the enterprise requisitions for purchase of commodities and services against the accounts of a customer company. In exemplary embodiment, extra net 394 may be a secure network, such as a frame relay network connection, or a secure protocol on the world wide web.
The method for creating and maintaining user profile table 384 is further described in copending application Ser. No. 09/815,318, filed Mar. 22, 2001.
Referring to FIG. 10 in connection with FIG. 7, associated with each company group resource 465, 467, 469 is a resource profile 466, 468, 470, respectively, containing a list, in the case of a catalog profile 466, of those companies, each associated with a company group, authorized to access catalog 465. This list may be maintained also at an item 471, 472 level.
As a user 451 logs in, his profile 461 code fields 482 and 481, respectively, will associate him with a given company 248 in a company group 242. When he clicks on shop-from-a-catalog button on his browser, catalog application code displays only those catalogs 465, 467 for which the profile 466, 468 includes his company in list 487 (this is at company level).
Other data that is similarly protected (other than catalogs), for example, include contracts 469, cost centers (departments that can be charged—a user can charge across companies 248, 249 in a company group, but not across company groups 243, 242), user profiles 384 (a user 451 may be able to initiate requests for other users 452—using button “change requester”, which will bring up people in his company group, if configured to allow it.) More examples of resources protected by resource profiles 465 are accounting GL accounts codes that are associated with commodity codes by company group. Business rules associated with that accounting that are company group specific—and include accounting business rule defaults, such as fields required to be filled out based on what is being bought.
A given catalog 465 may, as controlled by catalog profile 466, be associated with more than one company within more than one company group. Business rules may require a user in a particular company group to buy from a particular catalog or catalogs, and such user will only see those catalogs associated with his company group. Information and resources are isolated to users by company group by associating company group with each data item that exists in the various data files and code procedures (for which such isolation is required).
Vendors 246, 247 may transmit catalog information to their respective catalogs 467, 469 via EDI mailbox 455.
Req/Cat Web server 40 assembles requisitions from users in all company groups and transfers these to procurement services system 42, which issues purchase orders to vendors 246, 247 for orders against their catalog. Invoices back from vendors 246, 247 are sent, in this example, back to SAP 42 via EDI 44 mailbox 456.
Referring to FIG. 12, the manner in which purchases from users in different company groups are leveraged to achieve volume related costs with respect to leveraged contract 480 is described. As is represented by lines 61, users 450, 451 from different company groups may, in accordance with user profiles and catalog profile 466, as previously discussed, issue requisition requests against the same line item 471 in catalog 465. Other requests may be entered with respect ot other items 472. These requisition requests are transferred, as represented by lines 51, to SAP 42. SAP 42 periodically (say, hourly or daily) cuts purchase orders 474, 475 to vendor 246, with separate purchase orders for requisition requests from each company group. Invoices 478, 479 are returned to SAP 42 and bridged to RCW 40 for confirmation processing prior to payment. Negative or positive confirmation processing is executed by Req/Cat Web server, as is more fully described in copending application Ser. Nos. 09/815,318, filed Mar. 22, 2001, and 09/815,313, filed Mar. 22, 2001, respectively, with separate confirmation requests sent to users in different company groups—this, again, providing information segregation and protection. However, volume commitments against contract 480 are leveraged by purchase orders from all company groups having access to items in vendor 246 catalog 465.
Similarly, buys against contract 469 (for example, a blanket purchase order for services from a vendor 247) may be leveraged by company group.
In this way, the preferred embodiments of the invention isolate information and processing required across multiple company groups by using profiles (user profile and resource and process profiles such as contract and catalog profiles). There is a profile provided for every element, resource, procedure, data, line item, G/L account—everything of any kind for which leveraging and isolation is to be achieved across company groups.
