We use the above structure [or physical tables] with appropriate bBusinessObject.nBusinessObjectRole values to construct even more Sales Entities.

So, if we use the  Sales Shipment Entity with a nBusinessObjectRole= 3503 we create the Return of a SalesShipment !!

and if we use the Sales Payment Entity with a nBusinessObjectRole= 3102 we create the Return of a Sales Payment !!


You can find a complete list of nBusinessObjectRole values in the project area of the business applications.


*Note that, depending on the nBusinessObjectRole value, BPs are called to insert, update, delete or post Sales Entities and there is nothing special in the nBusinessObjectRole(s) values.
