Field help (BULAMTAPPB) 

Approved budgeted amount of the budget line, ex-tax. The approval of the budget line itself or the approval of its budget generates a "approved amount" of the budget line and makes it possible to enter purchases requests, orders and invoices on this line. This amount will not change after approval. Only the cancellation of the approval will reset this amount and the approval date on the budget line. The cancellation of the approval of a budget line is forbidden if its purchase requests, its orders or its invoices are entered.
