and an activity might have already been posted against it.

System Response

How to fix this error?

Use the <DS><DS:TRAN.FM5U>Change Fund transaction</></> to try to delete
all assignment(s) of this budget period to funds first. If there was
already an activity posted against this budget period in combination
