Haven't been able to find an answer to this one. I have a subform that is related to the main form by order number. In the subform, user will enter qty received for a po. Because we may not receive entire quantity for po at once, we need to add a number or letter to the end of the order number to indicate more than one received qty. So order number 1234 would be 1234-1 for first quantity, then 1234-2 for second qty. Does anyone have any ideas on how to accomplish this? Thanks for any help. I am using Access 2000.
