• What is the cause and solution for SAP error message /SCWM/CCHECK270 - Check: do TUs exist with identical external number and carrier ?

  The SAP error message /SCWM/CCHECK270 indicates that there are Transport Units (TUs) in the system that have identical external numbers and carriers. This situation can lead to confusion in logistics processes, as the system expects each TU to have a unique combination of external number and carrier.
  Cause:
  
  Duplicate External Numbers: The same external number has been assigned to multiple TUs, which can happen due to data entry errors or system integration issues.
  Carrier Duplication: The same carrier is associated with multiple TUs that share the same external number.
  Data Migration Issues: If data was migrated from another system, it’s possible that duplicates were introduced during the migration process.
  
  Solution:
  
  
  Identify Duplicates: Use transaction codes or reports in SAP to identify the TUs that have the same external number and carrier. You can use the following steps:
  
  Go to the relevant transaction (e.g., /SCWM/PRDI for displaying TUs).
  Filter or sort the TUs by external number and carrier to find duplicates.
  
  
  
  Correct Data: Once duplicates are identified, you can take the following actions:
  
  Delete or Merge TUs: If duplicates are not needed, you can delete the unnecessary TUs. If they need to be merged, ensure that the relevant data is consolidated correctly.
  Change External Numbers: If the TUs need to be kept separate, consider changing the external number of one or more TUs to ensure uniqueness.
  
  
  
  Review Processes: Investigate how the duplicates were created to prevent future occurrences. This may involve:
  
  Reviewing data entry processes.
  Checking integration points with other systems to ensure that they are not creating duplicates.
  Implementing validation checks during TU creation.
  
  
  
  Consult Documentation: Refer to SAP documentation or consult with your SAP support team for specific instructions related to your version of SAP and any customizations that may be in place.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes for managing TUs, such as /SCWM/PRDI (Display Transport Units) and /SCWM/PRDI (Create Transport Units).
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  User Exits and BAdIs: If your organization has custom logic for handling TUs, review any user exits or BAdIs that may affect TU creation and management.
  
  By following these steps, you should be able to resolve the error and prevent it from occurring in the future.
