Solved! Go to Solution.
You could try the other way around:
Open the WTPart with Manufacturing view and use then the 'Comapre to Part' action.
Since the view version did not give us the flexibility we needed if we needed to obsolete a view, we have actually gone a different route and added some customization to our process. Instead of using the views we added suffixes at the end to act as our view.
Thank you for the suggestions though.
