OK a little bit of background first. The organisation is set up with 7 users with 3 business units. Each of these business units are inherited from a parent so they should have the same security priviledges etc. Each business unit has a corresponding team (with no security roles attached). Each user has been assigned the same security role.
The problem is that a user in one of the business units is unable to see Cases in the main navigation bar. I have checked that the security roles are correctly configured to be able to create/read/update/delete Cases, however I cannot see any options for hiding entities from the main nav bar. Is there another setting somewhere that controls this? How can I get the Case options to appear again for this one user?
