I replied to a similar topic, but I thought I'd start a new one too. We are currently without an admin for Teamcenter Express (V5 running NX7.5), and hopefully we'll be updating to something else soon, but I need some help. We have several Items (not IRs) that were accidentally released. I have infodba access in the interim, but I need a quick workflow setup explanation to remove the release status. Can you help me? We have a quick release workflow, and I thought it would be easy to reference that one and reverse some steps, but that didn't go so well.
Not sure exactly what handlers you have access to in TCX, but here is a simple one step from UA.
Use the normal methods to attach targets to your workflow (probably already have this in your quick release already) like EPM-attach-related-objects on the start of the workflow.
Use EPM-set-status with the Argument -action and Value -delete
Hope that helps.
