• What is the cause and solution for SAP error message CNV_20100040 - No change of names wanted ?

  The SAP error message CNV_20100040: No change of names wanted typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This error indicates that the system has detected an attempt to change the name of an object (like a business partner, material, etc.) that is not allowed or not intended in the current context.
  Cause:
  
  Data Mapping Issues: The error may arise if the data mapping in the migration process is incorrectly set up, leading to an attempt to change an existing name.
  Configuration Settings: Certain configuration settings in the migration tool or the target system may restrict name changes for specific objects.
  Business Logic Constraints: The business logic defined in the system may prevent changes to certain fields or attributes, including names, to maintain data integrity.
  Duplicate Entries: If there are duplicate entries in the source data that conflict with existing entries in the target system, the migration process may trigger this error.
  
  Solution:
  
  Review Data Mapping: Check the data mapping configuration in the migration tool to ensure that you are not unintentionally trying to change names. Make sure that the source and target fields are correctly aligned.
  Check Configuration Settings: Review the configuration settings in the migration cockpit or the relevant transaction to ensure that name changes are allowed for the objects you are migrating.
  Data Cleansing: Cleanse the source data to remove duplicates or conflicts that may cause the migration process to attempt a name change.
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using to understand any restrictions or requirements related to name changes.
