User Management and User Roles 
For SAP NetWeaver PI, you use the standard SAP NetWeaver usage type AS User Management. You usually create users in the clients of the Integration Server.
In the following, a distinction is made between dialog users and service users that already have user roles for their maintenance.
Note
If you perform a client copy for a new business system, ensure that you also copy the user roles.
In addition, you can create more specific user roles by defining data-dependent authorizations for the Enterprise Services Repository and the Integration Directory, and assigning these authorizations to roles you create in user management.
