  SAP Error Message:
  
  VHUAP022 – Enter an item number for the purchasing document
  
  Cause:
  This error occurs when you attempt to perform an operation on a purchasing document (such as a purchase order, contract, or scheduling agreement) without specifying an item number. In SAP, many transactions related to purchasing documents require you to enter a valid item number to identify the specific line item you want to process or display.
  
  Explanation:
  
  Purchasing documents in SAP are structured with a header and multiple line items.
  Certain functions or screens require you to specify which item you want to work with.
  If the item number field is left blank or invalid, the system cannot proceed and throws this error.
  
  
  Solution:
  
  Enter a valid item number in the item number field when prompted.
  Verify the item number exists in the purchasing document you are working on.
  If you are unsure about the item numbers, you can:
  
  Display the purchasing document (ME23N or ME22N) to check the item numbers.
  Use the search help (F4) on the item number field to select a valid item.
  
  
  Ensure that the item number corresponds to an existing line item in the document.
  
  
  Additional Information:
  
  This message is common in transactions like ME22N (Change Purchase Order), ME23N (Display Purchase Order), or custom programs that process purchasing documents.
  If you are developing or debugging custom code or user exits/enhancements, ensure that the item number is correctly passed and validated.
  Sometimes, this error can appear if the document is incomplete or if the item was deleted or not yet created.
