Copying Authorizations for Other Users or Permission Groups 
You can copy authorizations between permission groups and between users. This function is especially useful in the following situations:
Between permission groups:
Members of two permission groups play similar roles in the company but are divided into two groups because they belong to different business units or branches.
There is considerable overlap between two permission groups in terms of members.
For example, Group A is included in Group B. Both groups require the same authorizations for nearly all permission items, except that Group A requires higher authorizations for certain permission items. As a result, you can first define authorizations for Group B, then copy Group B's authorization profile to Group A, and lastly, fine-tune Group A's authorizations.
Between users:
Two users play the same role and have exactly the same responsibilities. Therefore, they may have the same authorization profile.
Two users' responsibilities are very similar and differ only in a few aspects.
Note
You cannot copy any superuser's authorization profile for regular users. Although you can grant full authorization to a regular user throughout the system, only superusers can perform certain functions (for example, assigning authorizations, data ownership, and licenses).
Procedure
Note
If you want to copy authorizations only between two users or between two permission groups, you can use an alternative drag-and-drop method. For example, you can drag a user name to another user name, and then release the mouse button. This can also apply the first user's authorizations to the second user after your confirmation.
