Implementation of the configuration in the system
Administrators often need to replicate part or all of a database, for example, to create a system backup or test an upgrade before putting it into production. In the past, this was surprisingly difficult to do with most databases. With HANA, replication works instantly and provides richer functionality and better control than previous databases.
Whenever you find a red traffic light on the Roles tab in the user master in SU01 - or a yellow traffic light on the Users tab in PFCG, you can usually solve the problem with a simple user synchronization. The fact that such a user adjustment is necessary can have several reasons. Among others: after a role transport to / when assigning users to roles via PFCG after restricting the validity of roles to users when roles are assigned indirectly via organizational management. Users usually notice the problem of a user comparison that has not been carried out quite quickly: Authorizations are missing, although at first glance they are available in the assigned authorization roles. This is because a user is assigned the correct authorization role - but the profile associated with the role is not up to date.
The database layer manages all data in the R/3 System. It contains the database management system (DBMS) and the actual data.
The application layer is the core of an R/3 SAP Basis system. This layer communicates in both directions, to the presentation layer and to the database layer. The application programs on the application servers request the required data from the database layer, process it, prepare it for the user and pass it on to the presentation layer. Data that the user enters in the SAP GUI is passed on to the database via the application servers.
Tools such as "Shortcut for SAP Systems" complement missing functions in the SAP basis area.
In the default scenario, the support packages in the queue are fully loaded.
This includes several possible implementation variants: for example, SAP GUI for HTML (Web GUI) and Web Dynpro for ABAP (WDA).
