R12.1.3: Rejected PO mistakenly documents approval

Obviously the title catches your eye just the way it did mine as I thought I did not read it right the first time I saw it!  The content of My Oracle Support document "Purchasing Document was Rejected by the PO Approver, but it is found that the Status is Approved in the Action History" in note ID 1684684.1 actually is exactly what it says as rejected POs are instead documenting approval in the history lines due to a known bug.  Are you affected by this?  Repeat the steps as Oracle has shared them, and make sure you have already applied the bug fix to prevent data issues!
