Transaction KE1Z (transfer CO-PA planning to new GL)

Hello,

I executed the planning within CO-PA and want to transfer to new GL using transaction KE1Z).

Is there any documentation on how to set up new GL here.

I have plan version 1 vor CO-PA (costing based) and Ledger 0L with L1 in place in new GL.

Reason for my asking:

1KEZ is always green and selects the correct records from CO-PA.

But no data is written into table FAGLFLEXP.

Thanks a lot for any input.

Thomas
