This typically occurs during data migration processes, such as when you are trying to migrate location data into the SAP system, and the system finds duplicate entries for the specified migration key.
  Cause:
  
  Duplicate Migration Keys: The primary cause of this error is that the migration key you are trying to use is not unique. This can happen if the data being migrated contains multiple records with the same identifier.
  Data Preparation Issues: The data source from which you are migrating may have inconsistencies or duplicates that were not addressed prior to migration.
  Incorrect Mapping: There may be an issue with how the migration keys are mapped in the migration tool or process.
  
  Solution:
  
  
  Identify Duplicates: 
  
  Check the source data for duplicates. You can do this by querying the data source to find all records with the same migration key.
  Use tools like Excel or SQL queries to identify and list the duplicate entries.
  
  
  
  Resolve Duplicates:
  
  Decide how to handle the duplicates. You may need to merge records, delete unnecessary duplicates, or assign new unique migration keys to the records.
  Ensure that each location has a unique migration key before attempting the migration again.
  
  
  
  Adjust Migration Process:
  
  If you are using a migration tool, ensure that the mapping of migration keys is correctly set up to avoid conflicts.
  Review the migration strategy to ensure that it accommodates the uniqueness of migration keys.
  
  
  
  Test Migration:
  
  After resolving the duplicates, perform a test migration with a smaller dataset to ensure that the issue is resolved before migrating the entire dataset.
  
  
  
  Consult Documentation:
