• What is the cause and solution for SAP error message VL667 - You cannot create several dlv.headers in case of external no. assignment ?

  The SAP error message VL667, which states "You cannot create several delivery headers in case of external no. assignment," typically occurs in the context of creating outbound deliveries in the SAP system. This error is related to the handling of delivery documents when using external number assignment for deliveries.
  Cause:
  The error arises when the system detects that there is an attempt to create multiple delivery headers for a single delivery process while using external number assignment. In SAP, when external number assignment is configured, the system expects that each delivery will have a unique number assigned externally. If the system tries to create multiple delivery headers for the same delivery process, it violates this rule, leading to the error.
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check Delivery Creation Process: Ensure that you are not inadvertently trying to create multiple delivery headers for the same delivery. Review the process that leads to the creation of deliveries to ensure that it is correctly set up.
  
  
  Review Number Assignment Configuration:
  
  Go to the configuration settings for delivery document types in SPRO (SAP Customizing Implementation Guide).
  Navigate to Logistics Execution > Outbound Process > Delivery > Define Delivery Document Types.
  Check the settings for the document type you are using to ensure that external number assignment is correctly configured.
  
  
  
  Use Internal Number Assignment: If your business process allows, consider switching to internal number assignment for deliveries. This can be done in the same configuration area mentioned above. However, this may not be suitable for all scenarios, especially if external tracking is required.
  
  
  Check for Custom Code or Enhancements: If there are any custom developments or enhancements in your SAP system that might be affecting the delivery creation process, review them to ensure they are not causing the issue.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that might address this specific error. There may be patches or updates that can resolve known issues related to this error message.
  
  
  Testing: After making any changes, conduct thorough testing to ensure that the issue is resolved and that deliveries can be created without errors.
  
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like VL01N (Create Outbound Delivery) or VL02N (Change Outbound Delivery) to test the delivery creation process.
  Documentation: Refer to SAP Help documentation for more details on delivery processing and number assignment.
  User Roles and Authorizations: Ensure that the user roles and authorizations are correctly set up to allow for the creation of deliveries.
  
  If the issue persists after following these steps, it may be beneficial to engage with your SAP support team or consult with an SAP expert for further assistance.
