Ok, i've got an interesting one.(At least to me.) I have a script that tells the user that the item they just entered on on a Sales Order(Sage 100 ERP Advanced) has been superceded. It tell them the superceded number and the new number. And it was replacing the superceded number on the line with the new number. It stopped doing that in their live company. It still works in a test company. Script is running fine in both cases. It's just not overriding the item # in the live company. It will write the new item code to the comment text field. Any ideas? Oh btw the superceded number comes from a UDF on the item record.
