CNV_DMC_MC_EXCEPTION210 - Details

• The SAP error message CNV_DMC_MC_EXCEPTION210 typically occurs in the context of the SAP Data Migration Cockpit (DMC) when you attempt to change rules that have been defined at the project level. This error indicates that the rules you are trying to modify are locked or restricted because they are set at a higher level (project level) and cannot be altered at the current level (e.g., task level).
  
  Cause:
  
  Project-Level Restrictions: The rules you are trying to change are defined at the project level, which means they are intended to be consistent across all tasks within that project. This is a design choice to ensure data integrity and consistency during the migration process.
  User Permissions: You may not have the necessary permissions to modify project-level settings or rules.
  Incorrect Context: You might be trying to make changes in a context (like a specific task) where such changes are not allowed.
