Therefore, there can also be critical permissions, profiles, and roles that do not fit in the naming scheme defined by SAP. Manual identification of critical SAP permissions is difficult overall. However, tools are available that automatically check for critical permissions. In this case, the critical SAP permissions are usually predefined by special verification software. If the critical permissions, profiles, and roles are identified, they should be adjusted according to the permission planning. The system will then be checked to see if the desired system behaviour has been achieved or if malfunctions occur. This adjustment process may be complex in the event of major changes and should not be carried out on the production system.
