Open Document Link in PO Approve Notification Opens a Blank Purchase Order in 12.1.3

Hi

Open Document Link in PO Approve notification opens Blank Purchase Order.

Say, X is the approver for multiple Operating Units. When he gets the approval request for 3 POs realated to different OUs the following happens.

1. X opens the notification of OU 1 and clicks on the Open Document and the PO gets opened for review.

2. X opens the other OU(say 2) notification and when clicks on the Open Document, it doesn't ask for Responsiblity switch or opens the correct PO. It ends with Blank PO Form.

Any help on this appreciated.

Regards
