SAP Best Practices
Scenario Overview – 1
Purpose and Benefits:
Purpose


POS Inbound is a process of sending business information from SAP POS to SAP
ERP. It aims to explain the process of how the data transfer from SAP POS to SAP
ERP is done. It also intends to provide the list of business information or data that are
generated.
It describes the regular activity within the Retail POS Integration. Sales transactions,
created in SAP POS are in binary and is converted to ascii format. The SAP PI
handles the data conversion to IDOC format. SAP POSDM performs sales auditing,
data cleansing & optimization, then generates an aggregated IDOC and sends it to
SAP ERP.
Benefits


All POS transactions are processed via a single interface, ensuring complete tracking
of the process. Missing or duplicate transactions are automatically identified thru SAP
POSDM.
With the data and application integration, systems' functionality becomes more robust

Optimizing and streamlining processes increases overall efficiency
