How to restrict PO delivery date to weekdays?

Hi All,

  My factory calendar has all days (Including Week ends & public holidays ) as working days. In this case, some of my vendors prefer not to deliver on the week ends & public holidays. In the MRP run, system calculates PO delivery date using calendar days and it sometimes falls on weekends & public holidays.

  I'd like to know how can i restrict PO delivery date for certain materials to fall ONLY on WEEK DAYS.Your help on this is highly appreciated.

Thanks in advance.

Rgeards,
