</>. However, a sales document already exists with the number &V1&.

System Response

You can choose a number from the number range interval for internal
document number assignment, if you want to close the gaps between the
numbers assigned by the system. However, this is not possible if there
is already a sales document for the number you have chosen. The system
does not transfer this number for the new delivery.

How to fix this error?

Choose another document number, for which there is no delivery or
choose a document number from the number range interval for external
number assignment.
If necessary, contact your system administrator who will tell you which
document numbers are still free.

• What is the cause and solution for SAP error message VL346 - Number assignment is not possible; sales document &1 already exists ?

  The SAP error message VL346 ("Number assignment is not possible; sales document &1 already exists") typically occurs when you are trying to create a new sales document (like a delivery or sales order) that conflicts with an existing document in the system. This can happen for several reasons, including:
  Causes:
  
  Duplicate Document Number: The system is trying to assign a document number that is already in use for another sales document.
  Number Range Issues: The number range configuration for the document type may not be set up correctly, or the number range may be exhausted.
  Document Type Configuration: The document type you are trying to use may have restrictions or settings that prevent the creation of a new document.
  Data Entry Errors: There may be a mistake in the data entry that leads to the system interpreting the new document as a duplicate.
  
  Solutions:
  
  
  Check Existing Documents: Verify if the sales document number mentioned in the error message already exists in the system. You can do this by using transaction codes like VA03 (Display Sales Order) or VL03N (Display Outbound Delivery).
  
  
  Review Number Ranges: Go to transaction SNRO (Number Range Objects) and check the number range for the relevant document type. Ensure that the number range is correctly defined and that there are available numbers.
  
  
  Adjust Number Range: If the number range is exhausted, you may need to extend it. This can be done in transaction SNRO or by contacting your SAP administrator to adjust the number range settings.
  
  
  Check Document Type Settings: Review the configuration of the document type in transaction VOTXN or SPRO (IMG) under Sales and Distribution settings. Ensure that the document type is correctly configured and that there are no restrictions that would prevent the creation of new documents.
  
  
  Data Entry Verification: Double-check the data you are entering to ensure that there are no mistakes that could lead to the creation of a duplicate document.
  
  
  Consult SAP Notes: Sometimes, specific issues may be addressed in SAP Notes. Check the SAP Support Portal for any relevant notes that might provide additional insights or solutions.
