3152063 - Error in Purchase Order Approval: Enter an e-mail address in the output settings

On approving a Purchase Order, error occurs:

-Enter an E-mail address in the output settings
-Save failed; refresh list to perform further actions

Even when you send the order back to revision and enter the e-mail address in the "In Revision" Purchase Order and resend it, the system still throws an error while approving.
