• What is the cause and solution for SAP error message CNV_MBT_XAPP_A063 - Default values are saved for unassigned new logical system name ?

  The SAP error message CNV_MBT_XAPP_A063 indicates that default values are being saved for an unassigned new logical system name during a data migration or conversion process. This typically occurs in the context of using the SAP Landscape Transformation (SLT) or SAP Data Migration tools, where logical systems are used to identify different systems in the landscape.
  Cause:
  
  Unassigned Logical System: The error usually arises when a new logical system name is created but not properly assigned to a specific configuration or mapping. This can happen if the logical system is not defined in the system or if there is a mismatch in the configuration.
  Missing Configuration: The logical system may not have the necessary configuration settings or mappings associated with it, leading to the system defaulting to predefined values.
  Data Migration Settings: During data migration, if the logical system is not correctly set up in the migration settings, the system may not know how to handle the data for that logical system.
  
  Solution:
  
  
  Check Logical System Configuration:
  
  Go to transaction SCC4 to verify that the logical system is correctly defined in the system.
  Ensure that the logical system is assigned to the correct client and has the necessary settings.
  
  
  
  Assign Logical System:
  
  If the logical system is not assigned, you may need to assign it to the relevant configuration or mapping in the migration tool you are using.
  Use transaction BD54 to assign the logical system to the appropriate client.
  
  
  
  Review Migration Settings:
  
  Check the settings in the data migration tool (like LTMC or LTMOM) to ensure that the logical system is correctly referenced and that all necessary mappings are in place.
  Ensure that the source and target systems are correctly defined in the migration project.
  
  
  
  Default Values:
  
  If default values are being used, review what those defaults are and whether they are appropriate for your migration scenario. You may need to adjust these settings to align with your business requirements.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for the specific migration tool you are using for any additional configuration steps or troubleshooting tips related to logical systems.
