POS Interface - Inbound: Sales/Returns (Store) 
Use
This business process allows you to use the POS interface to process sales or returns which have taken place via POS systems in stores.
Merchandise in stores is normally sold via electronic cash registers (POS systems). These POS systems are often integrated into store retailing systems, too. Sales have to be communicated to the integrated functions of SAP Retail (for example, Inventory Management, Replenishment Planning, Financial Accounting, the Information System) so that the necessary information can be updated in the system.
Process Flow
Notes and Remarks

It is possible to configure your system in Customizing so that for each store, item conditions can be retrieved both from the stores (sales prices, discounts, etc.) and from master data. The item data from these two sources can then be compared and any differences can be determined. This is useful if your POS system can only provide retail price data and not discount data, for example.
If partial revaluation (see information on sales price revaluation) is possible in a store, the item conditions cannot be compared.
