  SAP Error Message:
  
  VN018 - Enter output medium
  
  Cause:
  The error message VN018 occurs when the system requires you to specify an output medium for vendor-related communications (such as payment advices, remittance slips, or correspondence), but this information is missing or not maintained in the vendor master data or the relevant output determination procedure.
  In other words, SAP expects you to define how the output should be sent (e.g., print, email, fax, EDI), but this has not been specified.
  
  When does it occur?
  
  During vendor invoice processing or payment runs.
  When generating payment advice notes or remittance documents.
  When output determination for vendor communication is triggered but the output medium is not defined.
  
  
  Solution:
  
  
  Maintain Output Medium in Vendor Master:
  
  Go to transaction XK02 (Change Vendor) or FK02 (Change Vendor Accounting).
  Navigate to the Payment Transactions tab.

  Enter the appropriate output medium, e.g.:
  
  1 = Print output
  2 = Fax
  3 = EDI
  4 = Email
  5 = Print with archive link
  
  
  Save the changes.
  
  
  
  Check Output Determination Procedure:
  
  Verify the output determination procedure for the relevant document type (e.g., payment advice).
  Ensure that the output medium is correctly maintained in the output condition records.
  Use transaction NACE to check output types and their medium settings.
  
  
  
  During Payment Run:
  
  When running payment program (transaction F110), ensure that the output medium is selected or defaulted correctly.
  In the payment run parameters, check the output options.
  
  
  
  Customizing:
  
  If the output medium is not maintained or available, check with your SAP FI/CO consultant or Basis team to ensure that the output medium values are configured properly in customizing under:
  
  SPRO ? Financial Accounting ? Accounts Payable ? Business Transactions ? Outgoing Payments ? Payment Medium ? Define Output Medium
