You can reject an order to stop Pearson (or your selected vendor) from filling it.

Prerequisites

You can only reject an order in Submitted status.

Step-by-Step 

  1. From Setup, go to Orders & Shipment Tracking.

  2. Under Find Orders Placed and Updated in, select a period of time during which reports occurred, and click Search.

  3. Click the checkbox next to the order.

  4. Click Select Tasks, select Reject Orders, and click Start.

  5. Type a reason.

  6. Click Reject.

Effects

The system retains a record of rejected orders, but the rejection is permanent. You cannot reinstate the order; you must create a new one.
