We have this scenario:
User is assigned to 2 business roles - Role A and Role B.
Role A has unique set of home page cards under Group 1
Role B has unique set of home page cards under Group 2
While logging on to system - user sees both groups - Group 1 and Group 2 , one below another
Question - Can the order of card groups controlled in this scenario?
For example - User to see Group 2 first and Group 1 below it (instead of default view as described below).
Why do your users have more then one business role? This can lead to access rights anomalies. I would advise to work with one business role per user, or at least do home page configuration for one business role per end user group.
You customize the home page per business role. Per business role you can add the groups and with in the groups by drag and drop you can change the order of the cards.
