One of my user facing one issue that PR is blocked but PO has been created and GR/IR also done. Our PR release strategy is item level. I checked the PR changes data but nothing has changed. I replicated same PR in test system then i tried to create PO but didnt get success, got error (PR is not released ) also in production system tried to create PO by taking same PR but didnt get success as PR is not released. But how user created the PO without releasing this PR. i checked change history but didnt get any changes. Could you please let me know, what will be the possible reason..
