Hi Experts,
I want to update the Customer PO field on VA01 while saving. The requirement is to update the customer PO(VBKD-BSTKD) while updating VBAK-BSTNK on VA01 screen as well as in VBKD table. I have written the code in SAVE_DOCUMENT_PREPARE to get the Customer PO from Z table and update the same in VBAK and VBKD. Now the issue is I am able to update it in VBAK but neither in VBKD nor on the screen. Also, tried X and Y VBKD structures but nothing works. Please help.
