The roles in the standard delivery correspond to the working environment of certain users. As these roles are only templates; that is, examples of work centers, you must still adjust these roles to the requirements of your users.
The predefined standard roles are delivered as templates. They begin with the prefix "SAP_".
Do not change the delivered standard roles (SAP_*), but rather only the copies of these roles (Z_*). Otherwise, the standard roles that you have modified will be overwritten by newly delivered standard roles during a later upgrade or release change.
The users must already exist in the system before you can assign them. For more information, see Creating and maintaining user master records.
The users to whom you have assigned the role can logon to the system. The user menu with the transactions, reports and internet links that they require for their work and for which they have been assigned the necessary authorizations, appears.
