Error custom project in 2020R1 "Revision code cannot be empty" after migration

@mohamed1walha,

Below is the sample to create the Sales Order through code. Hope this help!!

SOOrder newOrder = new SOOrder();
            newOrder.OrderType = "SO";
            newOrder = SOGraph.Document.Insert(newOrder);
            newOrder = PXCache<SOOrder>.CreateCopy(SOGraph.Document.Search<SOOrder.orderNbr>(newOrder.OrderNbr));
            newOrder = PXCache<SOOrder>.CreateCopy(SOGraph.Document.Update(newOrder));

            newOrder.CustomerID = BaseGraph.Document.Current.CustomerID;
            newOrder.CustomerLocationID = BaseGraph.Document.Current.CustomerLocationID;
            newOrder.OrderDesc = "CM Order Created for " + objSOOrder.OrderType + " :" + objSOOrder.OrderNbr;
