Part Revision for Sub Assembly was not found, request cancelled

Built an assembly, trying to “get details” in a quote. This is the error I am getting. The part it’s referring to is raw material, there is no revision for it. Not sure why I get this error? Do purchased items have to have a revision?

Check Out the top level part. Make sure that the Pull and Plan as assembly flags are unchecked on the material in question.

Thank you that did it!
