• What is the cause and solution for SAP error message VN2004 - Check for procedure & (assigned for header output) ?

  Certainly! Here's a detailed explanation for the SAP error message VN2004:
  
  SAP Error Message: VN2004
  Text: Check for procedure & (assigned for header output)
  
  Cause:
  The error message VN2004 occurs during output determination in the purchasing or invoice verification process. It indicates that the system cannot find a valid output procedure assigned for the header output in the document. This usually means:
  
  The output procedure is not assigned or maintained correctly in the customizing.
  The output type or procedure is missing or incomplete for the document type or vendor.
  The system is trying to determine an output but the configuration for the output procedure is missing or incorrect.
  
  
  When does it occur?
  
  During message determination for purchase orders, contracts, or invoice documents.
  When the system tries to find the output procedure for the header output but fails.
  Typically during printing or sending output (e.g., print purchase order, send email, EDI).
  
  
  Solution:
  To resolve the VN2004 error, follow these steps:
  
  
  Check Output Procedure Assignment:
  
  Go to SPRO ? Materials Management ? Purchasing ? Messages ? Output Control ? Message Output Determination.
  Verify that the output procedure is assigned to the relevant document type (e.g., Purchase Order, Contract).
  
  
  
  Maintain Output Procedure:
  
  Ensure that the output procedure contains the necessary output types (e.g., NEU for purchase order print).
  Check that the output types are correctly configured with the required access sequences, condition tables, and message determination.
  
  
  
  Assign Output Procedure to Vendor:
  
  Check if the vendor master record has the correct output procedure assigned or if the output determination is set up correctly for the vendor.
  
  
  
  Check Condition Records:
  
  Verify that condition records exist for the output type in question.
  Use transaction MN04 or MN05 to maintain or check condition records.
  
  
  
  Check Header vs Item Output:
  
  The error specifically mentions header output. Make sure the output procedure includes header output types if required.
  Sometimes output types are assigned only to item level but the system expects header level output.
  
  
  
  Debug or Trace Output Determination:
  
  Use transaction NACE (for older releases) or the newer output determination tools to analyze the output determination procedure.
  Check the logs or use debugging to see why the system cannot find the procedure.
