We have a weird issue, some products has the word 'copy' in a parenthesis at the end of its name in the description column on order lines. The actual name of the product doesn't have it. I know the description column uses the 'display_name' field along with some other things to generate that description but I have checked the 'display_name' on those products and that doesn't have that word either. I can't figure out why it is appearing and only on some. We have bunch of custom works but none of them modifies anything on order lines. This is both on SOs and POs.
check the sales description in Proeduct master under the Sales tab. Maybe the "copy" is included in that.
Nope, that is empty, no description added on any of the description field, there are just some things on Internal Notes which doesn't contains the word 'copy'.
