Call Stack Tab
The Call Stack tab identifies which service generated the error and lists its antecedents. Call Stack also identifies the flow step that executed when the error occurred. Results view contains a Call Stack tab only for a flow service and only if the flow service throws an exception.
Keep the following points in mind when looking at the Call Stack tab.
The call stack is LIFO based. That is, the top entry in the stack identifies the last (that is, most recent) service invoked. The bottom entry identifies the parent service (the one that you originally invoked from
Designer). If the parent itself throws the exception, it will be the only entry in the call stack.
You can go to the flow step that was executing when the error occurred by clicking
on the Results view toolbar. To view the service in Package Navigator view, right-click the service and select
Show In > Navigator.
