  Causes:
  
  No Data to Migrate: The source data might not contain any records that meet the criteria for migration.
  Data Already Exists: The target system may already have the data that is being attempted to be migrated, leading to no changes being made.
  Incorrect Mapping: The mapping of fields between the source and target systems may not be set up correctly, resulting in no data being identified for migration.
  Filters Applied: Filters or selection criteria applied during the migration process may exclude all records, leading to no changes.

  Check Source Data: Verify that the source data contains records that need to be migrated. Ensure that the data is correctly formatted and meets the requirements for migration.

  Data Validation: Check for any validation rules in the target system that may be preventing data from being migrated. Ensure that the data complies with these rules.
  Logs and Messages: Review the migration logs and messages for any additional information or warnings that may indicate why no changes were made.
