Re: Fixing Date and Quantity for Purchase order

Exception message 20 is triggered during the rescheduling check. Probably, this PO is outside the rescheduling horizon or excluded from the rescheduling check in customizing.

I suggest you to take a look on the following WIKI, in order to understand the rescheduling in more detail:
