Upgraded a Sage 100 Adv 4.30 to 4.50.4 today. Certain items are throwing an error in SO Entry. Error is 'Is not on File' - see attached pix. I click Ok and the cursor goes back to the item I entered. In DFDM, CI_Item, these items have a Primary Vendor Division (00) but no Primary Vendor # (and client doesn't want them to have a Pr. Vendor). Divisions are not turned on in AP either. Coworker indicated she has also come across this and removed the Div #. I can do that, and it works, but anybody know why this is happening and is this truly the fix or a workaround that we found to work but not really resolving the problem? I aso found some of the items have a 'Not on File' vendor in the Items Vendor Maintenance - see attached pix and it won't let me delete it except through DFDM. I did that but item still throws error in SO entry. I looked in 4.30 and the items have a Div # but no Vendor # but it doesn't throw the error, and the blank Item Vendor record is there in 4.30 too.
