shortfall of # days
when performing Automate the move from transit to scrap, there is an error message "shortfall of 137 days against....".
I checked the inb delivery, the batch has expiry date 9 Dec 2010, PO doc date is 16 Feb 2011, so the remaining shelf life is 2 months. When perform on 18 May 2011, it appeared shortfall of 137 days, I believe it is the total days from 9 Dec 2010 to 18 May 2011.
Question: what should I do to avoid the shortfall of # days? Does it solve the problem if I change the remaining shelf life in detail line of PO to 2 months instead of 0.
