If you Validate with NCOALink inside AccuZIP6 5.0, then presort and print the Mailing Statement, AccuZIP6 5.0 will add this date to the Maildat.seg file.“Required Field Missing: The .seg Move Update Date is required when the .seg Move Update Method is 1, 2, 3, or 5.”
If you do not process the list through NCOALink using AccuZIP6, and instead select the NCOALink or other Move Update Method options from the Mailing Statement Setup window, then the software will not place any values in the Maildat.seg file with regards to the Move Update Date. You would have to enter this date manually in that case.
