• What is the cause and solution for SAP error message RS2HANA_AUTH216 - DBMS user is not uniquely mapped ?

  The SAP error message RS2HANA_AUTH216: DBMS user is not uniquely mapped typically occurs in the context of SAP BW/4HANA or SAP BW on HANA when there is an issue with the mapping of database users to SAP users. This error indicates that the system is unable to uniquely identify a database user due to multiple mappings or configurations.
  Cause:
  
  Multiple Mappings: The error often arises when there are multiple SAP users mapped to the same database user in the SAP HANA database. This can happen if the same database user is assigned to different SAP users in the authorization settings.
  Configuration Issues: Incorrect or incomplete configuration in the user mapping settings can lead to this error.
  User Management: Changes in user management, such as adding or modifying users, can lead to inconsistencies in the mapping.
  
  Solution:
  To resolve the RS2HANA_AUTH216 error, you can follow these steps:
  
  
  Check User Mappings:
  
  Go to the SAP HANA Studio or use the HANA Database Explorer.
  Check the user mappings in the SAP HANA Database for the specific database user that is causing the issue.
  Ensure that each database user is mapped to only one SAP user.
  
  
  
  Adjust Mappings:
  
  If you find multiple SAP users mapped to the same database user, you will need to adjust the mappings to ensure that each database user is uniquely associated with a single SAP user.
  You can do this by modifying the user mapping in the SAP BW/4HANA system or directly in the HANA database.
  
  
  
  Review Authorization Roles:
  
  Ensure that the authorization roles assigned to the users are correctly configured and do not overlap in a way that causes ambiguity in user mapping.
  
  
  
  Recreate User Mappings:
  
  If necessary, you may need to delete and recreate the user mappings to ensure they are set up correctly.
  
  
  
  Consult Documentation:
  
  Refer to the official SAP documentation for user management and authorization in SAP BW/4HANA or SAP HANA for more detailed guidance.
  
  
  
  Check for Updates:
  
  Ensure that your SAP system is up to date with the latest patches and updates, as this can sometimes resolve underlying issues.
