You can assign flavors created with SAP Screen Personas to Web Dynpro ABAP applications or SAP GUI transactions that are integrated in the launchpad.
In order for the desired flavor to be displayed to a user or group of users, you have to make sure that it is assigned to these users or to their PFCG role.
To check to which user or role a flavor is assigned, you use transaction /PERSONAS/ADMIN.

An application can have more than one flavor, with each screen looking different if so desired.
