SAP PO
  Title: Cancellation of Invoice & Goods Receipt Document
 Sometimes the user may post GR & IR for a wrong PO.In such cases, we need to first
  cancel the invoice document & then material document of the PO.
 If payment is already done to vendor then FI department has to reverse the vendor
  payment before cancellation of invoice document.
 Business Scenario:
 Let us consider that by mistakenly GR & IR is already posted for the PO. Later, the stores
  department has decided to reverse both the documents so as to maintain the stock
  entries for the right PO.
  Let’s understand the above business scenario in SAP.
