this is my first post here so I am, in effect, a virgin and need you to be gentle with me!
I have created a new database using the Invoices template. I am entering my products in the Products area and in three instances I am getting a message stating that " "Part Number" is defined to contain unique values only".
My issue is that I only have 21 products entered so far and none of them share the Part Number I am attempting to enter. There is, clearly, something I am missing but I can't see what.
Attached is a screenshot showing the products list. It is the three products PY-ZKBA10, PY-ZKBA6 and PY-ZKBA8 that are experiencing the problem.
Can anyone please help?
