| - | This functor chooses one of two possible maps produced from different execution pipelines. | + | Picks the first available map from two possible execution pipelines, so a map still reaches the rest of the model even when one of the pipelines that could produce it does not run. |

| - | First, this functor verifies whether there is a valid input in "Possible Map 1"; if not, it chooses "Possible Map 2" as input. It is a convenient way to provide an alternate map in case an execution pipeline does not return a valid data. If "Possible Map 2" is not set, the functor will return a void output. | + | The inputs are checked in order — Possible Map 1, then Possible Map 2 — and the first one that has a map is passed to the output. If neither input has a map, the output is left without one, which allows chaining several junctions together to combine more than two possible pipelines. |

| + | This functor is typically placed after a container whose execution is conditional, such as [[If Then]] or [[Skip On Error]], so a default map is still available when that container's content does not run or does not finish. | ||
