How to disable end-users from seeing and editing their user mapping
We are implementing an external portal where all users are mapped to a generic system user for back-end access to SAP, but for security reasons, we do not want them to be able to see or change this system user.
The issue arises in that the users need to be able to change their user profile (i.e. email address, password, address, etc.), so I gave them access to the User Profile Web Dynpro iView (com.sap.portal.umeEnduserWD). I assigned the action UME.Manage_My_Profile for the portal role they use. Unfortunately, this action also gives them the ability to change their user mapping, which displays the system user. I also tried the action UME.Read_My_Profile and UME.Manage_My_Password, but this gives them read-access to their user mapping.
Is there a way to remove the User Mapping tab from the User Profile Web Dynpro iView?
