  Adjust the Quantity: If you need to change the quantity, ensure that it is equal to or greater than the delivered and invoiced quantities. If you need to reduce the quantity, you may need to cancel or reverse the existing goods receipt or invoice first.
  Use a Credit Memo: If you have invoiced quantities that need to be adjusted, consider using a credit memo to adjust the invoiced amount before changing the PO quantity.
  Consult with Your Team: If you are unsure about how to proceed, consult with your finance or procurement team to ensure that any changes comply with your organization's policies and procedures.
