I want to add Alternates to an Engineering Part. I go to the EC Part -> Related Parts -> Alternates -> Add Existing. But here in the Add Existing page, I dont get any parts to be added as Alternate to the EC Part in context. Even if I search for any part, it does not come up. The EC Part is in Draft state. I searched for the same type of EC Part. Can you help me on this? Thanks in advance.
