Upgraded customer on Friday night from 4.3 to 4.5 PU4. He's telling me today that when he creates a new item and tries to accept without a product line, it tells him 'product line is required' (as it should), however, if he then accepts again, it tells him 'primary vendor is required' but will not let him add the primary vendor. They can copy the IM item from another item and then they can add the primary vendor but not for a new item. I tried this in my PU3 and PU4 to make sure it didn't break but mine works just fine. He does have some UDF's in CI ITem but says he ran the update utilities and still getting this issue. Anybody have any ideas? Thanks.
