We have only 5 lines of X++ code in Visual Studio. You will create model (not shown in video). Then create new project Unified Operation, add new class. It is recommended that class name includes Extension suffix.
We create event handler for OnInitialized event in SalesTable form. The only thing it does is it retrieves SalesTable buffer and prints Sales Order Number or SalesId
It should take you five minutes to watch this video and begin your own event handlers programming
