Remove Dim bound table?

Hi

I have an assembly that has a dim bound reference to an old part name which has now been renamed. Subsequenly when I try to remove the old part, Intralink tells me I cant.

I found the reference using "Global reference viewer"

I can view the Dim Bound table which includes the old part but I cant delete it, the table that is. The Dim Bound menu has an option for delete dimension but I cant find the original dimension I created using the old part.

Thanks

Geoff
