• What is the cause and solution for SAP error message /VSO/M_MSG412 - Delivery number duplicate, delivery number=<&1> ?

  The SAP error message /VSO/M_MSG412 Delivery number duplicate, delivery number=<&1> indicates that there is a duplicate delivery number in the system. This typically occurs when you attempt to create or process a delivery that has the same delivery number as an existing one. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  
  Duplicate Entry: The delivery number you are trying to use already exists in the system. This can happen if:
  
  The delivery was already created and not properly processed.
  There was a manual entry error where the same delivery number was reused.
  The system settings or configuration allow for duplicate delivery numbers.
  
  
  
  Data Migration Issues: If data was migrated from another system, it’s possible that duplicate delivery numbers were imported.
  
  
  Custom Development: If there are custom programs or enhancements in place, they might be generating duplicate delivery numbers.
  
  
  Solution:
  
  
  Check Existing Deliveries: 
  
  Use transaction codes like VL03N (Display Outbound Delivery) to check if the delivery number already exists in the system.
  If it does, you may need to use that existing delivery instead of creating a new one.
  
  
  
  Use a Different Delivery Number: If the delivery number is indeed a duplicate, consider using a different number that is not already in use.
  
  
  Review Configuration: 
  
  Check the configuration settings in the system to ensure that the delivery number assignment is set up correctly. This can be done in the customizing settings under Logistics Execution.
  Ensure that the number range for deliveries is properly defined and does not allow for duplicates.
  
  
  
  Data Cleanup: If duplicates were created due to data migration or manual errors, you may need to clean up the data. This could involve deleting or archiving old or incorrect deliveries.
  
  
  Consult with Development Team: If you suspect that custom developments are causing the issue, consult with your ABAP developers to review the code and ensure that it handles delivery number assignments correctly.
  
  
  SAP Notes: Check for any relevant SAP Notes that might address this issue. Sometimes, SAP releases patches or notes that provide solutions for specific error messages.
  
  
  Related Information:
  
  
  Transaction Codes: Familiarize yourself with transaction codes related to deliveries, such as:
  
  VL01N (Create Outbound Delivery)
  VL02N (Change Outbound Delivery)
  VL03N (Display Outbound Delivery)
  
  
  
  Number Ranges: Understand how number ranges are configured in your SAP system. You can check this in the customizing settings under:
  
  SPRO -> Logistics Execution -> Shipping -> Basic Shipping Functions -> Delivery -> Define Number Ranges for Deliveries.
  
  
  
  Documentation: Review SAP documentation or help files related to delivery processing and error handling for more insights.
  
  
  By following these steps, you should be able to resolve the duplicate delivery number issue in SAP.
