## 2. Set the main / sub cancellation targets (when you use Cancellation)

Set which cart system or OMS an order is cancelled in once a cancellation is accepted. When both a cart system and an OMS are connected, Recustomer **checks the order status in each system** and **cancels the order** in the OMS first, then in the cart system.

1. Go to [Settings > External service integrations > Data integration settings](https://rcmr.io/settings/integrations/integration/target) and open the Exchange / Cancellation tab

2. Set the cancellation main to "select your integration" and the cancellation sub to "select your integration"
