  The SAP error message RS2HANA_AUTH123 indicates that there is a mapping issue between a BW (Business Warehouse) user and a DBMS (Database Management System) user in the context of SAP BW on HANA. This error typically arises when the BW user is not properly mapped to the corresponding database user, which is necessary for authentication and authorization purposes.
  Cause:
  
  User Mapping Issue: The BW user is not correctly mapped to the database user in the HANA system. This can happen if the user was created or modified without the necessary mappings.
  Authorization Problems: The user may not have the required authorizations to access the database or perform certain operations.
  Configuration Errors: There may be configuration issues in the BW system or the HANA database that prevent proper user mapping.
  
  Solution:
  
  
  Check User Mapping:
  
  Go to the SAP HANA Studio or use the HANA Database Explorer.
  Verify that the BW user is correctly mapped to the corresponding DBMS user. You can do this by checking the user settings in the HANA database.
  If the mapping is incorrect, you may need to create or adjust the mapping.
  
  
  
  Adjust Authorizations:
  
  Ensure that the BW user has the necessary authorizations to access the HANA database. This may involve granting specific roles or privileges to the user.
  You can do this by using the HANA Studio or SQL commands to grant the required permissions.
  
  
  
  Review Configuration:
  
  Check the configuration settings in the BW system to ensure that they are correctly set up for HANA connectivity.
  Make sure that the connection settings in the BW system point to the correct HANA database and that the credentials are valid.
  
  
  
  Recreate User Mapping:
  
  If the issue persists, consider deleting the existing user mapping and recreating it. This can sometimes resolve underlying issues that are not immediately apparent.
