I am importing into 2013 AR_DeleteChangeCustomers (I have learned the hard way about the speed when I actually process which is why I am working on this early in the weekend). I tested on 4.5 (a couple months ago) and we have since upgraded the client to 5.0. In 5.0 if I import the change number it tells me the item already exists and does not import the value. It does import the record (leaving me with an incomplete customer number). Any insight? Any way to change the validation? The record does work if I manually enter.
