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.

If you want to skip the backgrounds and prefer a direct step-by-step guide, you can jump directly into the last section. Preparation For this workaround, you need access to both the source system and the BW system. In addition, they shall have the possibility to access the SE37 and execute functional modules there. Especially in production systems this is a very critical justification. So assume that you may need a Firefighter user for this action. Working in the BW system Now that the preparations have been completed, you have to call a FuBa on the BW system and on the source system, which solves the connection on the respective page. Beginning on the BW system, go into the transaction SE37 and call the function block "RSAR_LOGICAL_SYSTEM_DELETE": RSAR_LOGICAL_SYSTEM_DELETE Enter the required values here. The following table helps you fill in: Field Description I_LOGSYS The logical name of the source system. The name of the source system, as found in RSA1, will be entered here. In addition, this name can also be found in the DB table TBDLT. I_FORCE_DELETE Boolean, X = Delete despite error messages I_NO_TRANSPORT Boolean, X = This change should not be transported to subsequent systems I_NO_AUTHORITY Boolean, X = Ignore Permission Checks Work in the source system In the source system, go to transaction SE37 and call the function block "RSAP_BIW_DISCONNECT" : The descriptions of the fields are as follows. These can be found in the RSBASIDOC source system connection table Field Description I_BIW_LOGSYS The logical name of the BW system. In the RSBASIDOC table, find the correct value in the column "RLOGSYS". I_OLTP_LOGSYS The logical name of the source system. The column ‘SLOGSYS’ in the table RSBASIDOC. I_FORCE_DELETE The logical name of the BW system. In the RSBASIDOC table, find the correct value in the column "RLOGSYS". Completion In the end, you have to call the respective function block in the BW and source system, fill in the parameters and execute the function block.

But when it comes to the intricacies of large SAP environments, Ansible quickly reaches its limits. If you want to use Ansible to implement simple automations - starting and stopping SAP environments, for example - you have to put up with a lot of manual effort and complicated scripts.

Since innovations through IoT (Internet of Things) or big data scenarios not only affect the SAP basis, but also highlight products and services for customers of their own company, the role of the SAP basis in relation to these scenarios and services must be clearly defined. In general, the SAP basis sees its responsibility here in the connectivity to the corporate network or the enterprise systems, which lie in the responsibility of the SAP basis. The support of the applications, based on the technologies as well as the associated services, is the responsibility of the respective department that offers this service. A SAP-based support service must be agreed and regulated during the conception.

With "Shortcut for SAP Systems" a tool is available that greatly facilitates some tasks in the SAP basis.

Those who have been trained as IT specialists can take advantage of further training to become SAP Basis Administrators and thus position themselves particularly well on the job market.
