• What is the cause and solution for SAP error message CNV_DMC_MC015 - Cannot delete field; only customer fields can be deleted ?

  The SAP error message CNV_DMC_MC015 indicates that you are trying to delete a field in a data migration context, but the field you are attempting to delete is not a customer-defined field. In SAP, only fields that have been defined by the customer (custom fields) can be deleted; standard fields provided by SAP cannot be removed.
  Cause:
  
  Attempting to Delete Standard Fields: The error typically occurs when a user tries to delete a field that is part of the standard SAP data model, which is not allowed.
  Data Migration Context: This error often arises during data migration processes, such as using the SAP Data Migration Cockpit or other tools, where users may attempt to modify the structure of the data being migrated.
  
  Solution:
  
  Identify the Field: Determine whether the field you are trying to delete is a standard field or a custom field. You can do this by checking the field's definition in the relevant data dictionary (SE11) or transaction code.
  Modify Migration Logic: If the field is a standard field, you will need to adjust your migration logic to exclude this field from the migration process instead of attempting to delete it.
  Use Custom Fields: If you need to remove a field, consider creating a custom field that can be deleted instead. This may involve extending the data model to include custom fields that meet your requirements.
  Consult Documentation: Review the SAP documentation related to the specific data migration tool you are using for any additional guidelines or best practices regarding field management.
