  Review ASN Data: Ensure that all data in the ASN is accurate and corresponds to the purchase order. This includes checking item numbers, quantities, and any other relevant details.
  
  
  Consult with IT or SAP Support: If the issue persists, it may be necessary to consult with your IT department or SAP support team to investigate further. They can check for any underlying issues in the system configuration or data integrity.
