I know, it might seem not logical, but I'm trying to get a sense of what the function of the GTIN number is in a Non-Inventory Sales Part.

I have added a Free Format GTIN on a Master Part. Let's say R-001

If I check the Non-Inventory Sales Part, it shows the R-001 as the GTIN. Nice.

When I want to add the sales part to a sales contract > line > item I have an option to search the parts by GTIN. Nice. However it seems only to pickup the Sales Parts (so the inventory related). Same on adding a non-inventory sales part on a work order task.

Am I missing something?

I can't select upon GTIN in a Customer Order Line that I want to add (there are only the part and description in the find option of sales parts which I think is remarkable low).
