When processing, you might come across the "Error: /rs/soap/shipment/v8: cvc-model-group 3: in element sender of type {http://www.canadapost.ca/ws/soap/shipment/v8}SenderType, required element company is missing" error.
This happens when you try to process an order using Canada Post as a carrier, and the Company Name field is empty for the account on the Client level.
To solve this problem you will have to:
- Access Clients under the Maintenance dropdown
- Select the Client related to the order and billing account in question
- Edit the billing account in question
- Select the Carrier Options tab
- Complete the Label from Company field
- Save to commit the changes
After doing so you should be able to process the order if the rest of the information related to it has been filled up correctly.
