1. Make sure the respective setting is enabled in Settings > Channel integrations > Edit channel details > Order > Despatch Notes. Full details on Cdiscount channel configuration are available here.
2. Cdiscount requires tracking numbers to be submitted when the buyer has selected either registered or tracked service. If no tracking number is submitted, then the Despatch Note will be rejected and the order will not be updated to the shipped status on Cdiscount.
To make sure tracking numbers are generated for registered or tracked services, select an appropriate Postal Service when generating the shipping label. Steps for making sure that tracking numbers are not missed can be found in this article.
