Need keep the company level -Unit price tolerance in the Accounts Payable parameter. Same as the “Purchase price total tolerance percent” & “Purchase price total tolerance”, system need keep a field “Unit Price Tolerance” in the Accounts Payable parameter to represent the company level tolerance. This field value should be synchronized with the line (condition: ALL (Item code) + ALL (Account Code)). The current poor design causes a big confuses for the user to understand and setup the “Unit price tolerance” and “Total price tolerance”.
