• What is the cause and solution for SAP error message CNV_DMC_MC082 - Mig. Obj. must start with a valid namespace:'Y' or 'Z' or '//' ?

  The SAP error message CNV_DMC_MC082 indicates that a migration object in the Data Migration Cockpit (DMC) does not start with a valid namespace. In SAP, custom objects typically need to be prefixed with 'Y' or 'Z' to distinguish them from standard SAP objects. The error message suggests that the migration object you are trying to use does not conform to this naming convention.
  Cause:
  
  Invalid Namespace: The migration object you are trying to use does not start with 'Y', 'Z', or a valid custom namespace (which usually starts with a forward slash followed by the namespace name).
  Typographical Error: There may be a typo in the name of the migration object.
  Configuration Issue: The migration object may not have been properly configured or created in the system.
  
  Solution:
  
  
  Check Migration Object Name: Ensure that the migration object name starts with 'Y', 'Z', or a valid custom namespace. For example, if your migration object is named MY_OBJECT, it should be renamed to Z_MY_OBJECT or Y_MY_OBJECT.
  
  
  Create a New Migration Object: If the migration object is not valid, consider creating a new migration object with the correct naming convention.
  
  
  Review Configuration: If you are using a migration object provided by SAP or a third-party, ensure that it is correctly configured and adheres to the naming conventions.
  
  
  Consult Documentation: Refer to the SAP documentation or the specific migration guide for the Data Migration Cockpit to ensure that you are following the correct procedures for creating and using migration objects.
  
  
  Check for Updates: Ensure that your SAP system is up to date, as there may be patches or updates that address issues related to migration objects.
