hi ramanjaneyulu,
I selected totals records only and got the message that the structure has been generated sucessfully.
The Special Ledger is not yet displayed in the DataSource Hierarchy in transaction SBIW.
the ledger was activated a few years ago but not used. We want to use the DataSource for a new Project with SAP BPC.
I found another article where it is stated that Transaction BW03MAST can be used aswell. I might try this and speak with FI-Team
Thanks for the help - the mainquestion (about the key) is anwered.
