I've created substitution and worklist for mass asset change. I released the worklist several hours ago in AR31. But when I refresh its status, it's still "In process" and nothing more happens. No background process is runnig in SM50, no SQL activity in system trace is visible, no changes are being made to any assets in the worklist.
When I test the same substitution and worklist for only one asset, it works OK.
Please, what can be wrong with the worklist?
