Why do I receive the error message 'Mandatory: Warehouse'?

The error message 'Mandatory: Warehouse' is generated by Exact Online when submitting an order. This message prevents the order from being sent from our CMS to Exact Online. The message indicates that Exact Online requires a warehouse code to be included with the order.

Steps to resolve the issue:

1. In the CMS, go to Administration > Settings > Connector settings tab.
2. Find the Warehouse used for order setting.
3. Enter the warehouse code.
4. Save the change.

After entering the warehouse code, it is necessary to perform an item synchronisation.
