Hi,
To be clear in the Retail Process the Every day sales data will be uploaded from the RMS - Retail Management System in .xml file format at the end of day into SAP through IDOC's . The IDOC's create the total sales process with all the details of Order, Delivery , Invoice ,Accounting Document and Stock updation etc.
Each Big Bazaar unit will represent a store in IS Retail .
Regards,
SRK
