This function stops the current mapping process with error message a.

Parameters

Parameter	Description
a	Error message.

Note: If you use a profile to act as a web service and you also use this function, the response of the web service will contain the content of parameter a and the stack trace. If you surround the error message with "§" characters, then only the error message will be returned, without the stack trace. A mapping test will still contain the exception message and the stack trace. Example: "§This is the error message§".
