Breakpoints provide a means of pausing task execution at specific steps of the task in order to examine variable states. Breakpoints can also be used to verify task execution flow by giving the user a chance to switch to stepping mode and proceed through the task step-by-step. When task execution reaches a step that has a breakpoint set on it, the Task Builder pauses the task before the step executes and waits until the user clicks the Run or Step button, at which point task execution continues.
Using breakpoints does not affect anything within the task itself
