• What is the cause and solution for SAP error message CNV_DMC_MC_EXCEPTION139 - Simulation not possible for migration objects that use staging tables ?

  The SAP error message CNV_DMC_MC_EXCEPTION139 indicates that a simulation is not possible for migration objects that utilize staging tables. This error typically arises during the data migration process when using the SAP Data Migration Cockpit (DMC) or similar tools.
  
  Cause:
  
  Staging Tables: The migration object you are trying to simulate relies on staging tables, which are temporary tables used to hold data before it is migrated to the target system. The simulation process may not support these types of objects because it requires a direct mapping to the target structure without intermediate steps.
  
  Configuration Issues: There may be configuration issues in the migration object setup that prevent the simulation from being executed properly.
  Data Integrity: The data in the staging tables may not meet the necessary integrity constraints or may be incomplete, leading to the inability to perform a simulation.
  
  
  Solution:
  
  Check Migration Object: Review the migration object configuration to ensure that it is set up
