Add record in system table before user define table
I have added Logic in GRPO Form's Add button for insert data in My Table
but data is insert in my table before insert into GRPO
giving example : like any validation fire first add data in my table before GRPO table because in system table data will add after validation.
I Want to Add Data first in SAP Table before my table.
suggest me if any one have solution for this kind of situation.
