It can be unclear as to which tier, either the client or the server, X++ code is executed on. This ambiguity can lead to problems. For instance if you run a server-bound batch, all of the code has to run on the server. If a call is attempted on the client this error will be thrown: “The server-side impersonated (RunAs) session tried to invoke a method that is available for client-side processing only.”
You can add statements to your class that will tell you which tier your code is executing on. Add the following to your X++ code:
info(strfmt(“%1”, xGlobal::clientKind()));
The output of this line will be either Client or Server.
