• What is the cause and solution for SAP error message CNV_MBT_XAPP_A057 - No logical system name maintained for receiver systems ?

  The SAP error message CNV_MBT_XAPP_A057 indicates that there is no logical system name maintained for the receiver systems in the context of a data migration or conversion process. This error typically arises during the execution of a migration project, particularly when using the SAP Landscape Transformation (SLT) or other data migration tools.
  Cause:
  The error occurs when the system is trying to identify a logical system name for the receiver system, but it cannot find any entry in the configuration. This can happen due to several reasons:
  
  Missing Configuration: The logical system name for the receiver system has not been defined in the system settings.
  Incorrect Settings: The logical system name may be incorrectly configured or misspelled.
  Transport Issues: If the configuration was transported from another system, it may not have been properly imported or activated.
  System Landscape Changes: Changes in the system landscape (like system copies or migrations) may lead to missing logical system definitions.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Logical System Configuration:
  
  Go to transaction code SCC4 (Client Administration) and ensure that the logical system names are correctly defined for all relevant clients.
  Ensure that the logical system name for the receiver system is correctly maintained.
  
  
  
  Maintain Logical System Names:
  
  Use transaction code BD54 to maintain logical system names. Here, you can add or modify the logical system names for the relevant systems.
  Ensure that the logical system name matches the one expected by the migration process.
  
  
  
  Check RFC Connections:
  
  Verify that the RFC connections to the receiver systems are correctly set up. Use transaction code SM59 to check the RFC destinations.
  Ensure that the logical system names used in the RFC connections are correct.
  
  
  
  Transport Requests:
  
  If the configuration was transported, check the transport logs to ensure that the transport was successful and that all necessary objects were included.
  
  
  
  System Landscape:
  
  If there have been recent changes to the system landscape, ensure that all systems are properly configured and that logical system names are consistent across the landscape.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation or notes related to the specific migration tool you are using for any additional configuration steps that may be required.
  
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or solutions for this specific error.
  Migration Tools: Familiarize yourself with the specific migration tools being used (e.g., SAP S/4HANA Migration Cockpit, SLT) as they may have specific requirements for logical system configurations.
  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 CNV_MBT_XAPP_A057 error and ensure that the logical system names are correctly maintained for the receiver systems.
