I wanted to add SaleInvoice using the SDK and found out that there is a method Company.Factories.SalesInvoiceFactory.Create(). But When I wanted to create PurchaseInvoice, I tried to look Create() Method in Company.Factories.PurchaseInvoiceFactory.  But there isn't any?

My question is, is there a support for creating PurchaseInvoice using the SDK on Sage SDK 50 U.S 2018?
