MailStream Plus- Using NDC PT to make both NDC and ASF entry points, and using EP MIN to move mail that doesn't meet the minimum quantities specified for an ASF entry point

A few NDC facilities have associated ASFs (which are sort-of like mini-NDCs).  With rare exceptions, mail that has a ZIP Code serviced by an ASF must be entered at that ASF in order to get the NDC discount.  Entering such mail at the parent NDC will not qualify for the DNDC discount.

The MailStream Plus EP MIN parameter considers the ASF level first, then EP MIN settings can be used to move the mail to the NDC it's associated with.  See EP MIN positions 40-44 and 46-50, and positions 68 and 70.
