I have checked all that I can see and I am completely baffled. If I change the value in a description field of a detail line item and then do a TableUpdate() it fails to update. It isn't even a key field. Any Ideas?

I am not double buffered. No base tables are opened in the DE or otherwise. I have narrowed it down to just this one field. I can make changes to all other fields in the row and the TableUpdate() works fine. If I change this field either using REPLACE or editing the field in a Grid it won't update.

TIA!
