srm purchase order automatic approval stuck on status "open (no decision made)" by system.
How can I kill the process?
When I trying to edit the order I get a message: "The document is still processing in the background, try again later".
If the workflow is not yet finished, then you can try the custom report from the note:
1458380-Restart process controlled workflow by ADMIN
If the workflow instance is indeed completed, then in a test case you can try to release it using the SWO1 - Set released method
(Some hints in the blog: https://blogs.sap.com/2017/02/18/srm-workflow-troubleshooting/)
This however many times will cause the document to became inconsistent. The best resolution for these kind of documents is to create a fresh one replacing it and delete the faulty one.
Hope this can help you in resolving the issue.
