• What is the cause and solution for SAP error message RS2HANA_AUTH412 - Maintained host is not equal to local host ?

  The SAP error message RS2HANA_AUTH412 indicates that there is a mismatch between the maintained host in the SAP system and the local host where the process is being executed. This error typically arises in the context of SAP BW (Business Warehouse) systems that are trying to connect to an SAP HANA database.
  Cause:
  The error occurs when the system is configured to connect to a specific host for the HANA database, but the actual host being used does not match the configured host. This can happen due to several reasons:
  
  Configuration Mismatch: The HANA database connection settings in the SAP BW system may not match the actual host name or IP address of the HANA database.
  Network Issues: There may be network issues or DNS resolution problems that prevent the SAP system from correctly identifying the HANA database host.
  Incorrect Host Entry: The host entry in the configuration might be incorrect or outdated.
  
  Solution:
  To resolve the RS2HANA_AUTH412 error, you can follow these steps:
  
  
  Check HANA Connection Configuration:
  
  Go to the transaction code DBACOCKPIT or RSADMIN in your SAP BW system.
  Navigate to the HANA database connection settings and verify that the host name or IP address is correctly configured.
  
  
  
  Verify Host Name:
  
  Ensure that the host name specified in the connection settings matches the actual host name of the HANA database server.
  You can use the command ping <hostname> from the command line to check if the host is reachable.
  
  
  
  Update Host Entry:
  
  If the host name has changed, update the connection settings in the SAP BW system to reflect the new host name.
  If you are using an IP address, ensure that it is correct and reachable.
  
  
  
  Check Network Configuration:
  
  Ensure that there are no firewall rules or network configurations that might be blocking access to the HANA database from the SAP BW system.
  
  
  
  Restart Services:
  
  After making changes, it may be necessary to restart the relevant services or the entire SAP system to ensure that the changes take effect.
