Thanks for the reply David. What if there is no CUSTNUM in the import file, but that customer does exist in the MOM database already? Will MOM just create it as a new account, even if the billing info matches an account already present?
Let me ask another question, which might make the need of the first one null and void. Is the CUSTNUM only needed if the billing and shipping information isn't present in the imported file? Or does the CUSTNUM field serve another purpose as well?
