Overview

Which formula versions would resolve to this lookup table if they ran now.

A variable names a table by key, never by id, and BuildLookups turns that key into a row through FindOwnedRecord — owner first, global second. So "does version X use table Y" cannot be answered by a foreign key or by matching keys alone: a global table is used by an owned formula only when that owner has no table of its own with the same key. Re-running the very same resolution is what keeps this answer from drifting away from what an actual calculation would do.
