Hi Sam,
Your COPA data source is generic data source.
Please take your FI/CO team help and find the base tables of your Operating concern.
In your case Operating concern is - OPC1.
We generally create/generate COPA data sources based on Operating concern.
Operating concern is created FI/CO team.
So please take your source team help and find the tables.
There 4 COPA tables which we can see data at source side CE1XXXX,CE2XXXX,CE3XXXX and CE4XXXX.
XXXX - refers your operating concern name.
Thanks
