Hello Sharvari,
Also check if user status needs to be defined for Appropriation Request in below config path
SPRO- Investment Management - Appropriation Requests - Master data - Control Data - User status - Define User Status Profile
Once this is defined, you need to assign it to App.Request type
SPRO- Investment Management - Appropriation Requests - Master data - Control Data -User status - Assign user status to Appr.Req.Type
Regards
