• What is the cause and solution for SAP error message CNV_DMC_MC_EXCEPTION142 - No simulation parameter defined in target structure ?

  The SAP error message CNV_DMC_MC_EXCEPTION142 with the description "No simulation parameter defined in target structure" typically occurs during data migration processes, particularly when using the SAP Data Migration Cockpit (DMC) or similar tools. This error indicates that the system is unable to find the necessary simulation parameters in the target structure that are required for the data migration process.
  Cause:
  
  Missing Configuration: The target structure may not have been properly configured to include the necessary simulation parameters.
  Mapping Issues: There may be a mismatch between the source and target structures, leading to missing parameters in the target.
  Incomplete Data Model: The data model for the target system may not be fully defined, which can lead to missing parameters.
  Version Compatibility: There may be compatibility issues between the source and target versions of the data structures.
  
  Solution:
  
  
  Check Target Structure Configuration:
  
  Ensure that the target structure is correctly defined and includes all necessary simulation parameters.
  Review the configuration settings in the DMC to ensure that all required fields are mapped correctly.
  
  
  
  Review Mapping:
  
  Verify the mapping between the source and target structures. Ensure that all fields in the source have corresponding fields in the target.
  If necessary, adjust the mapping to include any missing parameters.
  
  
  
  Update Data Model:
  
  If the target data model is incomplete, update it to include all necessary fields and parameters.
  Use transaction codes like SE11 or SE80 to check and modify the data model as needed.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for the Data Migration Cockpit to ensure that you are following the correct procedures and configurations.
