Why are we seeing the same billing and shipping address on every order to our site through CXML Punchout?

The Pressero CXML PunchOut integration can create any users on the site that the procurement system might use, but this is not enabled unless specifically requested when provisioning the CXML PunchOut setup for the site. The ability to do this is dependent on extrinsic fields containing unique user information being present in the return from the procurement system. If you have a CXML PunchOut enabled on your site and need this enabled, please submit a ticket to support.aleyant.com to request a change to your setup. For more information on cXML Punchout, please see the article cXML PunchOut.
