• What is the cause and solution for SAP error message ESH_INTEGRATION010 - 02/&1: Create reverse connection in back-end system ?

  The SAP error message ESH_INTEGRATION010 typically indicates an issue with the integration between the SAP system and the back-end system, particularly in the context of the Enterprise Search (ESH) or SAP HANA Search. The message suggests that a reverse connection needs to be established in the back-end system to resolve the issue.
  Cause:
  The error usually arises due to one of the following reasons:
  
  Missing Reverse Connection: The back-end system does not have a reverse connection configured for the front-end system.
  Configuration Issues: There may be misconfigurations in the connection settings between the systems.
  Network Issues: Network connectivity problems could prevent the systems from communicating properly.
  Authorization Issues: The user or service account may not have the necessary permissions to establish the connection.
  
  Solution:
  To resolve the error, you can follow these steps:
  
  
  Create Reverse Connection:
  
  Go to the back-end system (e.g., SAP ERP or SAP S/4HANA).
  Use transaction code SM59 to access the RFC destinations.
  Check if the reverse connection (RFC destination) exists. If not, create a new RFC destination that points back to the front-end system.
  Ensure that the connection type is set correctly (usually type T for TCP/IP connections).
  
  
  
  Check Configuration:
  
  Verify the configuration settings in both the front-end and back-end systems.
  Ensure that the logical system names are correctly defined and that the systems can recognize each other.
  
  
  
  Test the Connection:
  
  After creating the reverse connection, test it using the Connection Test feature in transaction SM59 to ensure that it is working correctly.
  
  
  
  Check Authorizations:
  
  Ensure that the user or service account used for the connection has the necessary authorizations to access the required resources in both systems.
  
  
  
  Review Logs:
  
  Check the system logs (transaction SLG1) for any additional error messages or warnings that might provide more context about the issue.
  
  
  
  Consult Documentation:
  
  Refer to the official SAP documentation or notes related to ESH integration for any specific configuration steps or troubleshooting tips.
  
  
  
  Related Information:
  
  SAP Notes: Search for relevant SAP Notes in the SAP Support Portal that might address specific issues related to ESH integration.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they found effective.
  System Version: Ensure that you are aware of the specific versions of SAP you are working with, as integration steps may vary between versions.
  
  By following these steps, you should be able to resolve the ESH_INTEGRATION010 error and establish the necessary reverse connection between your SAP systems.
