Client Query - Identical PO Number

Client Query - Identical PO Number

Problem

Two sales orders have the same customer PO number, how can I enforce a unique value?

Solution

It is not possible to enforce unique values for Customer PO numbers for sales orders. The reason for this is that the customer has control of this number and it is more than possible that two customers are purchasing from you for the same project, i.e. building renovations, road works etc.
