We are intending to use external operations during wafer assembly, at multiple levels of the build. We use discrete orders. Using external operations on the router, I see at order release that a purchase req is created. However, the Material Field of the PR is blank and unable to be edited when I click into it to view/change. Additionally, I cannot figure out how to convert this PR to a PO because usually I do this from MD04, but since the PR is not on a material, it doesn't appear on my MD04 screen. I don't see any option to release the PO.
Any advise would be greatly appreciated! Thanks!
