We use the Change Master CC01, CC02, to record all revision changes to materials. We don't currently use the full ECR capability, just simple change masters. For pre-production changes I to to the Objects tab and put a note in the Description field for each object (material or BOM) listed, noting an engineering request number that's generated and tracked externally.
I had hoped that this would allow me to search for all materials changed by request #123, etc but I hadn't actually tested it. I now see that there doesn't seem to be a way to search change masters by that text.
Am I missing something? Is there a way to search on the description field for objects across all change masters? I'll stop adding notes if I can't search for them.
