  SAP Error Message: VN366
  Message Text:
  
  Error when creating mail data for output during repeated run
  
  Cause
  The error VN366 typically occurs during the output processing of vendor-related documents (such as purchase orders, scheduling agreements, or invoice verification outputs) when the system tries to create mail data for output in a repeated run (i.e., when the output is processed again for the same document).
  Possible causes include:
  
  Duplicate output processing: The output determination tries to create mail data again for an output type that has already been processed, leading to conflicts or inconsistencies.
  Inconsistent or missing communication data: The vendor master or output configuration might lack proper communication details (e.g., email address, communication method) required for mail output.
  Incorrect or incomplete output configuration: Output types or partner functions may not be correctly set up for repeated processing or mail output.
  Buffer or internal table issues: Sometimes, internal tables or buffers used during output processing may contain inconsistent data during repeated runs.
  Authorization or system inconsistencies: The user or system might lack necessary authorizations or there might be system inconsistencies affecting output processing.
  
  
  Solution
  To resolve the VN366 error, consider the following steps:
  
  
  Check Output Determination and Configuration:
  
  Verify the output type configuration in transaction NACE (or the relevant output management transaction).
  Ensure that the output type supports repeated processing and mail output.
  Check if the output type is set up correctly for the communication medium (e.g., email).
  
  
  
  Verify Vendor Master Data:
  
  Check the vendor master record for correct and complete communication data (email address, fax number, etc.).
  Ensure that the partner function used for output has valid communication details.
  
  
  
  Review Output Processing Logs:
  
  Use transaction ME9F (Message Output: Purchase Orders) or the relevant output processing transaction to check the status and logs of the output.
  Identify if the output has already been processed successfully or partially.
  
  
  
  Delete or Reset Output Records if Necessary:
  
  If the output has been processed incorrectly or partially, consider deleting the output record and reprocessing it.
  Use transaction ME9F to delete output messages or reset the output status.
  
  
  
  Check for OSS Notes and Patches:
  
  Search SAP OSS Notes for any known issues related to VN366.
  Apply relevant patches or corrections if available.
  
  
  
  Debug or Analyze the Output Program:
  
  If the problem persists, debugging the output program or function module responsible for mail creation might be necessary.
  Check for custom enhancements or user exits that might interfere with output processing.
  
  
  
  Authorization Check:
  
  Ensure the user running the output has the necessary authorizations for output processing and communication.

  SAP Notes:
  
  Check SAP Support Portal for notes related to output processing errors and mail output issues.
  
  
  
  Output Types and Communication:
  
  Output types define how documents are sent (print, fax, email).
  Communication data must be maintained in vendor master or partner functions.
  
  
  
  Repeated Run Context:
  
  Repeated run means output is processed again for the same document.
  Some output types or configurations may not support repeated mail output without resetting or deleting previous output.
