• What is the cause and solution for SAP error message CNV_DMC_MC_EXCEPTION140 - Simulation not possible for migration objects that use transaction LTMOM ?

  The SAP error message CNV_DMC_MC_EXCEPTION140 indicates that a simulation for migration objects using the transaction LTMOM (Legacy Transfer Migration Object Modeler) is not possible. This error typically arises during the data migration process when using the SAP Data Migration Cockpit (DMC) or the SAP S/4HANA Migration Cockpit.
  Causes:
  
  
  Incompatible Migration Object: The migration object you are trying to simulate may not be compatible with the simulation feature. Some migration objects may have specific requirements or dependencies that prevent simulation.
  
  
  Missing Configuration: The migration object may not be fully configured or may be missing necessary settings or mappings that are required for simulation.
  
  
  Technical Issues: There could be underlying technical issues, such as missing authorizations, incorrect settings in the DMC, or issues with the underlying data model.
  
  
  Data Issues: The data being used for the simulation may not meet the necessary criteria or may contain inconsistencies that prevent the simulation from being executed.
  
  
  Solutions:
  
  
  Check Migration Object Configuration: Ensure that the migration object is correctly configured in LTMOM. Verify that all necessary fields, mappings, and settings are in place.
  
  
  Review Documentation: Consult the SAP documentation for the specific migration object you are using. There may be specific notes or guidelines regarding simulation.
  
  
  Test with Different Data: If possible, try running the simulation with a different set of data to see if the issue persists. This can help identify if the problem is data-related.
  
  
  Check Authorizations: Ensure that the user executing the simulation has the necessary authorizations to perform the operation.
  
  
  Consult SAP Notes: Look for relevant SAP Notes that may address this specific error. SAP frequently updates its knowledge base with solutions to common issues.
  
  
  Contact SAP Support: If the issue persists after trying the above solutions, consider reaching out to SAP Support for further assistance. Provide them with detailed information about the error and the steps you have taken.
