Dear FI Expert,

I want to entry document via FMBBC (budgeting workbench), after i entry version 0 and press enter, it showed error :

No status assigned to version 0 in FM area BSW1

Message no. FMCU006

Diagnosis

You want to use version 0 in FM area BSW1 but there is no status assigned to version 0 in FM area BSW1.

Procedure

If you want to use this version with this FM area, please maintain the settings under Assignment of Status.

You can also select another version for budgeting in this FM area instead.

I click Assignment of Status (tcode FMBOSTAT),but I can't choose one of status, how to maintan the status?

Thank you.
