Prior to Release 4.0, you had to specify the material document number in order to enter areturn delivery.
As of Release 4.0A, you can enter a return delivery without knowing the material document number. If you have entered a delivery note for a goods receipt for purchase order, the system automatically finds the material document for the delivery note. This is of particular benefit in goods-receipt-based Invoice Verification.
On the return delivery initial screen, you can enter the delivery note number in the delivery note field.
