We have created a buyer role with access to the function "Enterprise Buyer Inbox". Once the role is assigned to a test user, we can log in to SRM and the "Start Enterprise Buyer Inbox" shows up on the menu, and everything is ok. However, as soon as we add other SRM roles to the test user, the option in the menu goes away. I have traced the user in both occasions, and the same authorizations are being checked, for which I can't determine how the addition of the roles is affecting the availability of the "Start Enterprise Buyer Inbox" in the Menu.
Any ideas about it?
Thank you very much for your help!
