I don't think that is the way that this connection works. In Concur, there are "Partner Apps" that you need to activate. Just having your MP number in Concur doesn't trigger that behavior for my company. I've had it in Concur for years and don't see the "Business" choice in the UA app or website. I believe that integration is a fairly new option (maybe earlier this year?). If you go into Concur, there is a "Partner Apps" section and you can see what connections you have enabled. You are supposed to be able to disable the connection, but I can't find where. The only connection I have enabled is Uber, and when I open that section of the site, there is no "disconnect" button.
