• What is the cause and solution for SAP error message VN423 - MESSAGE object (mail output) does not exist ?

  The SAP error message:
  VN423 MESSAGE object (mail output) does not exist
  typically occurs in the context of output determination for purchasing documents (like purchase orders) when the system tries to find a message object for a mail output type but cannot find it.
  
  Cause
  
  The message object for the mail output type is not defined or missing in the system.
  The output type configured for the purchasing document is set to use a message object that does not exist or is incorrectly maintained.
  The output determination procedure for the purchasing document is referencing a message object that is not available in the system.
  Sometimes, this can happen if the output type is set to use a mail output but the corresponding message object (which controls the output processing) is not created or assigned.
  
  
  Explanation
  In SAP MM (Materials Management), output types (like print, fax, email) are linked to message objects that control how the output is processed. For example, message object NEU is often used for purchase order outputs.
  If the system tries to process an output type that requires a message object (e.g., for email output) but that message object is not defined in the system, it throws the error VN423.
  
  Solution
  
  
  Check Output Type Configuration:
  
  Go to transaction NACE (Output Types).
  Select the application (e.g., EF for Purchase Orders).
  Check the output type that is causing the issue.
  Verify the Message Object assigned to the output type.
  If the message object is missing or incorrect, assign the correct message object.
  
  
  
  Verify Message Object Existence:
  
  Use transaction SE91 (Message Maintenance).
  Enter the message object name that is assigned to the output type.
  If it does not exist, you need to create or correct the message object.
  
  
  
  Adjust Output Determination Procedure:
  
  Check the output determination procedure for the purchasing document type.
  Ensure that the output types assigned are valid and have correct message objects.
  
  
  
  Check Mail Output Configuration:
  
  If the output type is for mail output, ensure that the mail output configuration is complete.
  Check if the mail output is supported for the message object.
  Sometimes, mail output requires additional configuration in SCOT (SAPconnect Administration).
  
  
  
  Transport or System Copy Issues:
  
  If this error appears after a system copy or transport, verify that all message objects and output types have been transported correctly.
