make to order scenario, at the time of PO we dont have sale order, based on forecast client buying the rawmaterial,procurement takes 30 to 40 days,at the time of GRN we have the sale order, so my client wants to enter sale order no at the time of GRN.
is it possible in SAP?
at the time of PO account assignment E, sale order no is not mandatory(change the standard) but GRN time i can't enter saleorder no. the field is display mode? what to do?
