I have common scenario where we make Contract > Sale order >Delivery+PGI>Billing
1. We book contract on the name of Agent i.e. in Contract Sold to party and Ship to Party remains the same.
2. While making Sales order we change the Ship to party on the main screen.
3. But all the time our Payer is same as Ship to Party and for that we have to change partner function at header level of Sales order all the time manually
4. But, we want to have that while changing ship to party at sales order, payer should get automatically changed with same code as ship to party
5. Please help me if there is any possibilities in customization or some other type of solution.
