I created a workflow for purchase requsition, and my set up is that once the PR is approved, it will automatically generate PO. I want to see the purchase requisition ID on my PO header so I can easily see the PO generated from PR. I move the PR ID from PO line to PO header. However, I cannot move it to the GRID. I tried creating another field on the Grid for PR ID but it does not show the actual PR ID for a certain PO but it shows a drop down with all PR ID to choose from. This is not what I want.
Thanks for the help.
