While PO Receive in mobile device Exp date is mandatory suddenly in D365FO

Hi,

Issue: While PO Receive in mobile device Exp date is mandatory suddenly and

ASKING FOR THE EXP DATE ON THE 2ND SCREEN WAS STRANGE and IT WOULD NOT LET USER PROCEED WITHOUT ENTERING EXP DATE AND IT WAS THE ONLY ITEM WITH THAT SCREEN.

Solution: Go and check the Shelf life period for this item if its empty and update it with value. Its mandatory in Item Master.
