To add a system to the Systems view in SAP HANA, which methods are applicable?

The method involving a database user different from your ABAP user is crucial for adding a system to the Systems view in SAP HANA. This approach emphasizes the need for separate credentials to access the specific database, ensuring that the connection remains secure and that appropriate permissions are correctly assigned.

Using a dedicated database user for actions such as this prevents potential conflicts or security issues that may arise if both applications and database access were handled by the same user. The database user must have the right privileges to establish a connection and perform operations within the HANA database, which aligns with best practices for maintaining secure access to systems.

This method is particularly pertinent in complex environments where distinct roles for ABAP, database administration, and application services are necessary to maintain both functionality and security.

Regarding the other choices, while they may involve aspects of system integration or security management, they do not specifically address the requirements for adding a system to the Systems view in a targeted manner. Hence, the emphasis on having a separate database user highlights a key principle in managing system access within the SAP HANA environment.
