Screen enhancement in va01
I appended one structure with one field field1 of component type char1 to the table VBAK. That field is added to the subscreen(Header-add data A). Default value to be assigned to that field VBAK-field1 with out going to that screen.
while creating sales order even if he doesn't open that subscreen default value value must be saved to that table while saving tha sales order using usr exit.
First of all is it possible using user exit not customer exit because there are no SAP standard enhancements are available for this scenario.
