  Error Message
  WTADDI222: No messages exist for generated purchase orders
  
  Cause
  This error occurs in the SAP system when you try to process or output purchase orders (POs), but the system cannot find any message records assigned to those purchase orders. In other words, the purchase orders have been created/generated, but no output messages (such as print, email, EDI, or fax messages) have been defined or generated for them.
  Common reasons include:
  
  No output message has been maintained or generated for the purchase order.
  The output determination procedure for purchase orders is not correctly configured.
  The purchase order is missing the necessary output type or medium.
  The output message was deleted or not created due to configuration or master data issues.
  The user is trying to reprocess or display messages, but none exist for the PO.
