This document discusses how to cancel orders individually, in bulk, and check cancelled orders on an e-commerce platform. It provides steps to cancel a single order by selecting the order and cancellation reason from the Confirm & Pack tab. To cancel multiple orders, a seller can download the orders as a CSV file, select orders using checkboxes, choose a cancellation reason and upload the file. Cancelled orders can be viewed on the Orders tab by selecting the Cancelled tab and will show as Merchant Cancelled if cancelled by the seller or Cancelled if by the customer.
