RE: When creating Sales Order, how to prevent entering of the same Customer Purchase Order Number?
Hello Everyone,
There have been instance that the same Customer PO was process twice. Meaning there was two Sales Order made from the same Customer PO. We want to prevent this from happening. Is there a way to prevent or notify when the user is creating the Sales Order and the user input the Customer Purchase Order, the system should be able to detect if there is a duplicate Customer PO. Or there is already and existing Customer PO.
Looking for your kind response
Is there also an example for 2.x ?
