I am inserting orders on Sage 200 through an application using the client side, C# and APIs.
I would like to check the "Full payment" checkbox on the "Payment with order" tab.
Currently, I am setting the PaymentType property, which is not working.
order.PaymentType = Sage.Accounting.SOP.SOPOrderPaymentTypeEnum.EnumSOPOrderPaymentTypeFull;
order is an instance of Sage.Accounting.SOP.SOPOrder.
Do you know how I can check that property?

The following method should supply the required results.
