• What is the cause and solution for SAP error message CNV_20100458 - No data was changed ?

  The SAP error message CNV_20100458: No data was changed typically occurs during data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools. This message indicates that the system attempted to update or insert data, but no changes were made to the database.
  Causes:
  
  No Changes Detected: The data being processed may already exist in the target system in the same state, leading to no changes being detected.
  Data Validation Issues: The data being migrated may not meet the validation rules set in the target system, causing the system to skip the update.
  Mapping Issues: Incorrect mapping of fields between the source and target systems can lead to situations where the data does not change.
  Duplicate Records: If the data being migrated contains duplicates that already exist in the target system, the system may not perform any updates.
  Configuration Issues: There may be configuration settings in the migration tool that prevent changes from being applied.
  
  Solutions:
  
  Review Data: Check the data being migrated to ensure that it is different from what already exists in the target system. If the data is identical, no changes will be made.
  Check Mapping: Verify that the field mappings between the source and target systems are correct. Ensure that all necessary fields are included and correctly mapped.
  Data Validation: Ensure that the data meets all validation rules in the target system. If there are validation errors, correct the data before migration.
  Remove Duplicates: If duplicates are causing the issue, clean the data in the source system to ensure that only unique records are migrated.
  Log Analysis: Review the migration logs for any additional error messages or warnings that may provide more context on why no changes were made.
