Replace WT part A with a WT part B in all BOM structures in WIndchill

[KSHITISH_S]

I have a WT part RMT246 and a WT part RMT489. The RMT246 is being part of various BOM structures. I need to replace this RMT246 with RMT489 wherever it is used. Maintaining the alternate and replace each structure is taking lot of time. Is there a faster method.

You can use the mass change command. This is only available in the change notice/task

Mass Change

This works perfect for a WTPart structure. As soon CAD Documents are attached, it will be more complex and probably easier to exchange in CAD.
