In the SAP NetWeaver BI Authorization Concept lesson, the training participant is familiarized with the authorization functions of the SAP Business Information Warehouse. The differences between the authorization concept for ERP systems and the authorization concept for NetWeaver BI are taught.
Database layer: All of a company's data is stored in the database, which is located on a database server. Application programs pull the data they need from the database. This data can consist of data tables, applications or system control tables. In addition, the database also takes new information from users and backs it up.
Troubleshooting and fault elimination
SAP Basis consultants are experts in consulting. The job of an SAP Basis consultant has many areas of responsibility such as:
Regular maintenance tasks or the standard procedures must be described and defined to build checklists based on them and to control compliance with this standard. The SAPSolution-Manager can also support this as a tool of SAP e.g. through the Guided Procedures. In this context, it is also necessary to document the functionality of an underlying application and thereby determine what testing and monitoring activities are necessary. This is a reconciliation process between the SAP basis, other IT departments and, if necessary, the business areas concerned. The defined standard and the system's IST situation must be fully documented and regularly checked for compliance. This can be done through automated monitoring, validation using tools such as SAP-LVM (Landscape Virtualisation Management) or SAP Solution Manager, as well as manual checklists. Only the regular review of the standards guarantees their compliance. It can also support the regular use of SAP services such as Go-live Checks or Early Watch. Examples of how to standardise procedures are listed here: ・ Naming of system instances and logical hosts, or at least one central registry in a directory service, or LVM or SAP customer portal ・ Centrally starting and stopping systems, such as via the LVM ・ Categorising SAP instances by T-shirt size to define profile standards and cost them.
Tools such as "Shortcut for SAP Systems" are extremely useful in basic administration.
In concrete terms, this means that the message server takes care of load balancing and determines, for example, on which application server a user logs on.
In the past, when we deployed SAP environments, we first had to work out a detailed sizing and architecture and pass it on to the procurement team, which then ordered the systems and installed them in the data center.
