I have new requirement in creation of sales order . Here we have free promotion sales . Here if customer buy one material then he will get some other material as free .In standard sap we can give only one line item as free not more than that .
Here our requirement is more than one line item . I suggested them maintain all the free materials in one Ztable when ever the original material will come for sales order then i have to fetch these materials from ztable automatically and it should create sales order. I started doing this using user exit FORM USEREXIT_MOVE_FIELD_TO_VBAP.
These are the below links i checked in our sdn.
Please give me some idea on this .
