Error: Supplier id {DUNS=#########; } found in the catalog file does not match the subscription supplier's supplier id or any supplier id. Using supplier from subscription.

I am receiving the above error message when trying to upload a PunchOut Catalog into my SAP Business Network Production environment. I have already confirmed both in the buyer’s Business Network and in the supplier’s Business Network sides that the number is correct.
