SAP Note 16769 - FSE5 -> EM: Delete existing set 0F first

Symptom:

When you make the preparations for FI planning (transaction FSE5, program RFSPLN00), an error message is issued:
GS057 "Delete existing set 0F for table GLU1 first"
A basic set 0F then exists for table GLU1.

Cause and prerequisites

Error in the balance sheet version that is to be used for generating the set hierarchy in planning. The cause of this error is, in turn, an error in the program for maintaining the balance sheet versions.

Solution
Correct the program error as described in note no. 12433.
Then clear out the balance sheet version (please contact the FI Hotline if you require assistance).
Then repeat the preparations for FI planning.
