My scenario is as follows :
A contract of value 3000/- from 01.11.07 to 30.11.07 against which a sales order is generated for a value of 1400 (10.11.07 to 24.11.07). I will bill the sales order and for the balance 16 days i want to bill the contract directly for 1600/- or automatically generate a sales order and further billing. Is it possible through standard or with the help of ABAP'ers. Please advise.
