Effective this Friday September 30th we will be adding an additional field to the end of the order export. The new field name is Cancelled and this will display either a yes or no value depending on whether the order has been cancelled or not.
The expectation is that since this field is being added to the end of the order export it will not cause issues with existing integrations with the order export files.
If you believe that you will have a problem with this change and would like to discuss it further with our technical staff please create a support request.
