@Jackie_Braith unfortunately ReqNum isn’t on any of the PO tables Header,Detail and Rel that I’ve seen at least.
Are you needing to see the Req Number on PO Entry or Tracker?
The first thing that thing that comes to mind is adding a tab on the tracker screen through Sheet Wizard. Then have it display a dashboard that you made with all of the Req details. Here’s an example below.
Note, on the BAQ/Dashboard I only brought over a few fields but you can bring over as many as you would like.
Another way is to add a UD Field and add the req number there with a BPM but that would be more work then the route suggested above.
Let me know if you have any questions.
