This scenario describes a streamlined ("lean") version of merchandise procurement that can be used by a store without connection to an R/3 system to procure merchandise offline.

The following R/3 components are used:

Use of an instore distributed retailing system (DRS).

The instore system transfers requirements to the central R/3 system on the basis of requests for merchandise or the replenishment requirements that have been calculated for the store. When the central R/3 system processes the store orders, the store orders are converted into vendor orders, warehouse orders or deliveries.

Once the store has received the merchandise, the instore system sends the goods receipt data to the central R/3 system using IDocs, so that Invoice Verification can be carried out centrally, for example.

Data about sales, returns and special goods movements is sent by the instore system to the central R/3 system in IDocs. This data is used in a variety of functions, including Inventory Management, Replenishment and the Information System.
