Requirement is to split the sales order line items into multiple based on certain requirement. I Started coding in MV45AFZZ (USerexit_Save_Document_Prepare). Basically what i am doing is looping at XVBAP and based on some condition inserting additional line in XVBAP and adding a new line with new UOM and incrementing the POSNR.). The data seems to be ok to me. But when i save i am getting update terminated error. Can anyone help me out ?
