The order service in the system currently does not provide a 'Cancel Order' function, so the 'Cancel' and 'Restore' buttons on both the detail page and list batch row are disabled and display 'Feature not yet supported' when hovered over. For unwanted orders, you can use: • Still under negotiation: directly modify the content and send it, or explain the situation in 'Discussion' with the other party. • Definitely not needed: click 'Delete' to move to archived (orders can be unarchived later to recover); if you are sure it will not be used again, go to the archived list and 'Permanently Delete'. If you see a red message on the list saying 'The other party has cancelled this order', it means the other party's version was cancelled. Please confirm with the other party and decide whether to archive or continue handling on your end.
