Approved Part Revision for subassembly was not found - why do I need a revision on a purchased part?

We had a problem in that our traveler told us to pull something out of stock that we don’t stock. The simple fix I thought was simply to mark the part as pull as assembly so we’d get a second assembly on the job to build this part. The problem is when I try to create a quick job I’m getting the error below.

I can confirm I don’t have any revisions on the part the error references(see screenshot below), it’s a purchased part so I don’t understand why I need a revision… Any ideas?

Please disregard, I see the issue is the subassembly is a purchased part. I thought it was a manufactured part which contained this purchased part…

Cockpit problem on my end.
