Your company has two business units: BU1 and BU2. Each has a warehouse associated with it: W1 and W2, respectively. W1 has transferred the required material to W2 along with an intercompany invoice. On receiving the material, W2 finds that the material has a defect, and decides to scrap it in its warehouse, which is more cost-effective than sending it back to W1. But BU2 wants a credit from BU1 against the invoice amount that is already paid to BU1 because the material was defective and not consumed.
What action would you need to take to address this business requirement?
