  Correct Invoice Reference: If the invoice is meant for a different PO, ensure that the correct PO number is being used.
  Consult with Finance Team: If you suspect that the invoice should not have been posted yet, consult with your finance or accounts payable team to clarify the situation.
  Use Transaction Codes: Use transaction codes like FB03 (Display Document) to view the posted invoice and confirm its details.
