Hi,
You can use Get Items to retrieve items from another list. You could potentially have a lookup column on you rdocument library that points at the metadata item otherwise you would not have a way to match them together.
Hi @blueicebummer,
Could you please share more detail about your requirements?
What is the relationship between the two lists? How do you input the attachment into the approval? Create a Sharing link?
