This is how to unpick the items on the pick list: When an MO is RELEASED you can not change the status of the Mo because the items are on a PICKLIST. To remove the PICKLIST you need to open the MO: Transactions > Manufacturing>Entry...Enter the MO #, Click on the screen in the upper right hand corner with the arrow pointing down > Select PICKLIST...IN this window click the DELETE BUTTON to delete the picklist. At this point you are able to go back to the MO Entry screen and change the status to Cancelled or simply Delete the MO.
I HAVE VERIFIED THIS BY DOING IT MYSELF TO CORRECT THE MO ERROR I HAD.
