====== Table Junction ======

===== Description =====

Picks the first available table from two possible execution pipelines, so a table still reaches the rest of the model even when one of the pipelines that could produce it does not run.

===== Inputs =====

^ Name  ^ Type  ^ Description  ^
| Possible Table 1  | [[Table Type]]  | Table produced by one possible execution pipeline.  |
| Possible Table 2  | [[Table Type]]  | Table produced by another possible execution pipeline.  |

===== Optional Inputs =====

None.

===== Outputs =====

^ Name  ^ Type  ^ Description  ^
| Table  | [[Table Type]]  | Table picked.  |

===== Group =====

[[Functor List#Control | Control]]

===== Notes =====

The inputs are checked in order — Possible Table 1, then Possible Table 2 — and the first one that has a value is passed to the output. If neither input has a value, 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 table is still available when that container's content does not run or does not finish.
