Added Comment Field and Changed Signature of AddOrderExternalData Method

In the API V7Preview7, a field Comment has been added to the order, and the method IEditSession.ChangeOrderComment is used to change its value.

The signature of the method AddOrderExternalData has been changed — a flag isPublic has been added.

Data recorded using the AddOrderExternalData method with the isPublic flag set to true will become available in SyrveRMS for export in the OLAP sales report. If the isPublic flag is passed as false when calling the AddOrderExternalData method, such data will, as before, be saved only in SyrveFront and will not be accessible externally.
