• What is the cause and solution for SAP error message ESH_HANA_ADMIN242 - Logical system ID for CDS connectivity is not unique - &1 &2 &3 &4 ?

  The SAP error message ESH_HANA_ADMIN242 indicates that there is a problem with the logical system ID used for Core Data Services (CDS) connectivity in your SAP system. Specifically, it suggests that the logical system ID is not unique, which can lead to issues in data retrieval and processing.
  Cause:
  The error typically arises due to one of the following reasons:
  
  Duplicate Logical System IDs: There are multiple entries in the system with the same logical system ID, which can occur if the system has been incorrectly configured or if there are remnants of old configurations.
  Incorrect Configuration: The configuration settings for the logical system IDs may not have been set up correctly, leading to conflicts.
  Transport Issues: If transports have been incorrectly managed, it may lead to duplicate entries in the system.
  
  Solution:
  To resolve the issue, you can follow these steps:
  
  
  Check Logical System IDs:
  
  Go to transaction SICF and check the logical system IDs configured in your system.
  Use transaction BD54 to view the logical system IDs and ensure that each ID is unique.
  
  
  
  Remove Duplicates:
  
  If you find duplicate entries, you will need to remove or rename them to ensure that each logical system ID is unique.
  You can delete or adjust the configuration in the relevant tables (e.g., T000, TMS, etc.) to resolve the duplicates.
  
  
  
  Review Configuration:
  
  Ensure that the configuration for the logical systems is correct. This includes checking the settings in the SAP HANA Studio or SAP GUI.
  Verify that the logical system IDs are correctly assigned to the respective systems.
  
  
  
  Transport Management:
  
  If the issue arose after a transport, check the transport logs to identify any issues that may have occurred during the transport process.
  Re-import the transport if necessary, ensuring that it does not introduce duplicate logical system IDs.
  
  
  
  Restart Services:
  
  After making changes, restart the relevant services or the entire system to ensure that the changes take effect.
