Send Document Info Record along with Production Order to a Vendor

Situation:

I have a Document Info Record(DIR) which has drawings attached it as Originals. Now this DIR is linked to Material Master in the Object Links Tab. When I create a production Order for this material, an Idoc is generated which includes a hyperlink for this DIR. If I open this link, it requires SAP credentials which cannot be shared with our 3rd party Vendor.

Question:

What is the recommended way to send this DIR attachment to third party vendor? Basically the end goal is that the vendor should be able to access the Originals.
