When you have defined an automation server as a variable, you must use CREATE Function (Automation) to create an instance of the server. After that, you can use the server through the variable. You can browse its methods and properties in the Symbol menu.
When you are using a server, you should know that there is not a one-to-one relationship between C/AL data types and COM data types. For an overview of the data type mapping, see Using COM Technologies in Microsoft Dynamics NAV.
