  This warning message appears when a supplier number (vendor number) is required but has not been entered in a transaction or screen. The system expects a valid supplier/vendor number to proceed, and since it is missing, it prompts the user to enter it.
  
  When does it occur?
  
  During procurement or invoice processing transactions (e.g., ME21N, MIRO, FB60).
  When creating or changing purchase orders, goods receipts, or vendor invoices.
  In any screen or field where the supplier/vendor number is mandatory but left blank.
  
  
  Solution:
  
  Enter a valid supplier/vendor number in the required field.
  If you do not know the supplier number, use the search help (F4) to find the correct vendor.
  Ensure the vendor master data exists and is active in the system.
  If the supplier number is supposed to be defaulted automatically but is missing, check the configuration or master data setup.
