CNV_DMC_SIN515 - Details

• The SAP error message CNV_DMC_SIN515 ("Changing of already existing values is not allowed") typically occurs during data migration or data conversion processes, particularly when using the SAP Data Migration Cockpit (DMC) or similar tools. This error indicates that the system is trying to change a value that already exists in the target system, which is not permitted under the current configuration or rules set for the migration process.
  
  Cause:
  
  Duplicate Values: The error often arises when the migration process attempts to insert or update records that already exist in the target system with the same key or unique identifier.
  Data Integrity Constraints: The target system may have constraints that prevent the modification of existing records, such as primary key constraints or unique constraints.
  Configuration Settings: The migration settings may be configured to disallow updates to existing records, which can lead to this error if the migration process attempts to do so.
