• What is the cause and solution for SAP error message CNV_DMC_HC009 - &1 - &2: Synonym not created in target system ?

  The SAP error message CNV_DMC_HC009 typically indicates that a synonym could not be created in the target system during a data migration process. This error is often encountered in the context of SAP Data Migration Cockpit (DMC) or during the execution of a migration project.
  Cause:
  The error can occur due to several reasons, including:
  
  Database Permissions: The user executing the migration may not have the necessary permissions to create synonyms in the target database.
  Existing Synonym: A synonym with the same name may already exist in the target system, which can prevent the creation of a new one.
  Database Configuration: There may be issues with the database configuration or connectivity that prevent the creation of synonyms.
  Incorrect Target Schema: The target schema may not be correctly specified, leading to issues in creating the synonym.
  Database Type: Different databases have different rules and syntax for creating synonyms, and the migration process may not be handling these correctly.
  
  Solution:
  To resolve the CNV_DMC_HC009 error, you can take the following steps:
  
  
  Check Permissions: Ensure that the user executing the migration has the necessary permissions to create synonyms in the target database. This may involve granting the appropriate privileges.

  Review Database Configuration: Ensure that the database is properly configured and that there are no connectivity issues. Check the database logs for any additional error messages that may provide more context.
  
  
  Correct Target Schema: Verify that the target schema is correctly specified in the migration settings. Ensure that the schema exists and is accessible.
