İm using BAPI_SALESORDER_CREATEFROMDAT2 for sales order create. And after that i need to update serial number. When i use IWOL_WV_ADD_OBJECTS and IWOL_WV_POST_OBJECT_LIST for update serial number those Fm's not giving error. But i cant create delivery with FM:BAPI_OUTB_DELIVERY_CREATE_SLS.Fm saying there is something missing in sales order. When i check sales order which is i created with bapi and check error log its saying there is not serial number. But when i check serial number in extras-->technical objects i can see serial number. And when i try to go back sales order and check again error log there is not any error. İ think if i use batch i can fix this but i need to fix that with bapi or something. Tnx for help already..
