unit and unit serial issue on PO
I encountered a wired issue recently. Normally, on a PO, if there is a unit over there, I will be asked to put a valid unit serial which is associated with that unit. However, I found a user who is able to put anything in unit and unit serial field on PO. I logged into the same user account under a test environment which is mirrored from production database, it turned out I could even put random letters for unit and unit serial on a PO.
I tried to look at the authorization and other item settings, but I couldn't find any clue.
Anybody got any idea?
