In the course of digitizing purchasing processes, a web-based eProcurement solution from a third-party provider must be connected to an SAP ERP system. Communication between the back end and the eProcurement solution takes place indirectly via SAP PO. The data exchange takes place online via an IDOC interface on the one hand and via the provision of text files on the other. In addition to the installation on the back-end side, the scope of tasks includes customizing, documentation, coordination and execution of E2E tests.
An ABAP report extracts account assignment objects from the ERP system into a text file, which is transferred to the eProcurement solution via SFTP. Vendors can be created and maintained in the ERP system as well as in the eProcurement solution. The exchange of vendor data between the ERP system and eProcurement is based on the classification of suppliers. All suppliers classified in the back-end are transferred to the eProcurement system using an IDOC scenario. New suppliers created in the eProcurement solution are correctly classified using the ALE scenario. To create purchase orders in the ERP system, the eProcuremnt solution calls BAPIs from the third-party vendor.
The eProcurement solution not only enables purchasing to handle its procurement processes, it is also available to employees. The eProcurement solution integrates the product range (e.g. catalogs) of the suppliers. Users can access these and place their orders directly with the supplier and create the transaction in the ERP system.
