We are performing "migration budget documents" from Former budgeting to BCS in the middle of the year.
Budget type for normal budgeting is NB01 and Budget Type for release budget is RB01.
When the transaction code is executed in test run we gave NB01 as the budget type for normal documents and RB01 as the budget type for release documents. But NB01 is shown as budget type for all the documents in the screen and error message is displayed stating that NB01 budget type is not allowed for release transactions.
Budget type NB01 is not allowed for process ENTR for Release
Message no. FMCU016
You want to use budget type NB01 in combination with process ENTR for Release.
However, this combination is not permissible.
Please choose another budget type.
My question is when i have given RB01 as the budget type for release why system is checking for NB01.
