Exists

The purpose of this function is to test if one or more fields exist (are non empty) or do not exist (are empty).

If at least one field matches the desired condition, action processing will be paused and the Pending Action dialog will be presented. You can make whatever changes you desire and resume the action. Alternately, you can cancel the action step and continue. While batch processing, the fact that the condition was met will be logged.

The Exists Test variant of this function is used to return a test result as opposed to displaying the Pending Action Window or logging the condition.
