  The SAP error message "CNV_DMC_MC_EXCEPTION153 Import Simulation finished with errors" typically occurs during the data migration process using the SAP Data Migration Cockpit (DMC). This error indicates that there were issues during the import simulation phase of the data migration, which can prevent the successful transfer of data from the source system to the target system.
  Causes:
  
  Data Validation Issues: The data being imported may not meet the required validation rules or constraints defined in the target system.
  Mapping Errors: There may be discrepancies in the mapping of fields between the source and target systems.
  Missing Required Fields: Some mandatory fields in the target system may not have corresponding values in the source data.
  Data Type Mismatches: The data types of the fields in the source and target systems may not match, leading to conversion errors.
  Configuration Issues: Incorrect configuration settings in the DMC or the target system can lead to errors during the import simulation.
  Technical Errors: There may be underlying technical issues, such as database connectivity problems or system resource limitations.
