Using conditions in a collection

Add conditions to your collection to support multiple paths of execution.

At run time, a condition evaluates an expression or the results of a function alias. If the returned value equals true, the condition is met and the step or action that immediately follows is processed.

All conditions use the primary page of the collection. They do not use context page of the step.
