Hi Prasad,
In account based COPA the line items are stored in ACDOCA. Table COEP has been replaced by a HANA compatibility view for reading that is redirected to read data from table ACDOCA and map it to the COEP structure.In costing based COPA the line items are stored in CE1XXXX (actual) and CE2XXXX (planning) where 'XXXX' denotes the operating concern.The PA segments are stored in CE4XXXX.
Before defining the report, using "KEBC" t.code set type of COPA and use same transaction code during execution of the report also to select type of COPA. hence report will report data accordingly.
Thanks,
Rau
