Costing based CO-PA datasource
I am trying to set up a link bewteen costing based CO-PA and SAP BI to analyse data determined in SAP R3 system. The business wants to use a summarization level as datasource. In order to create summarization level datasource without selecting line items apart from the Record Currency (REC_WAERS), what are the necessary steps do I need to peform? Will the system create generic delta datasources or do we need to convert them to generic delta? Please could you point me to the right direction?
Thanks for your help.
