I have a running promotion request that I need to abandon or stop so that I can replace an approver with another approver. My thought was to simply abandon the running workflow and start over.
If you created it, just select the PR and delete it.
The files will be returned to their prior state.
Any admin can also do it.
if you have enough access rights:
promotion request action menu: "reassign life cycles", check "Use initial state of Life Cycle template" .
disclaimer: side effects are possible as you are about to terminate the original workflow.
