• What is the cause and solution for SAP error message ESH_SQL_SEARCH006 - Session client in HANA is different from the current ABAP system client ?

  The SAP error message ESH_SQL_SEARCH006 indicates that there is a mismatch between the client used in the HANA database session and the client of the current ABAP system. This error typically arises in scenarios where the SAP Enterprise Search (SAP ESH) is being used, and it is trying to access data in the HANA database but finds that the client context is different.
  Cause:
  
  Client Mismatch: The most common cause of this error is that the HANA database session is connected to a different client than the one being used in the ABAP system. In SAP, a client is a self-contained unit with separate data and configuration.
  Configuration Issues: There may be configuration issues in the connection settings between the ABAP system and the HANA database.
  User Context: The user context under which the HANA session is running may not match the expected client context.
  
  Solution:
  
  
  Check Client Settings:
  
  Ensure that the client in the HANA database session matches the client of the ABAP system. You can check the client in the ABAP system using transaction SCC4 and in HANA using SQL commands.
  
  
  
  Adjust Connection Parameters:
  
  If you are using a custom connection or a specific user to connect to HANA, ensure that the connection parameters specify the correct client. This may involve adjusting the connection string or settings in the relevant configuration files.
  
  
  
  Use the Correct User:
  
  Make sure that the user used to connect to the HANA database has the appropriate authorizations and is set up for the correct client.
  
  
  
  Restart the Session:
  
  Sometimes, simply restarting the session or the application can resolve transient issues related to client mismatches.
  
  
  
  Check for Configuration in ESH:
  
  If you are using SAP Enterprise Search, check the configuration settings in the ESH administration to ensure that the correct client is being referenced.
  
  
  
  Consult SAP Notes:
  
  Look for any relevant SAP Notes or documentation that may provide additional insights or patches related to this error.
  
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for Enterprise Search and HANA for detailed configuration guidelines.
  Transaction Codes: Familiarize yourself with transaction codes like SCC4 (Client Administration) and DBACOCKPIT (Database Cockpit) for monitoring and managing database connections.
  SAP Community: Engage with the SAP Community forums for discussions and solutions shared by other users who may have encountered similar issues.
  
  By following these steps, you should be able to resolve the ESH_SQL_SEARCH006 error and ensure that the client contexts are aligned between your ABAP system and the HANA database.
