Hi @sunilramakumar The formulae tip says that the Override amount and Override method line item will not be editable unless you check Submit Purchase Order Request and Override Shipping Method and Override Amount are TRUE (checked) in INV01 Module. Refer the pic, In Week2, only Submit Purchase Order Request is checked, so you will not be able to edit the override amount or override method line item. In Week3, Submit Purchase Order Request and Override order suggested amount are checked, so the override amount is editable. In Week4, Submit Purchase Order Request, Override order suggested amount, Override shipping Method are checked, so both override amount and override method are editable. Solution: In the module AD02, create those suggested line items as boolean and no need of any access driver(Write/Read) in this module. In the module, INV01, only provide write access driver to Override Suggested Order Amount, Override Amount and override Method Refer the attachment, I hope this helps, Thanks, Nivetha K
