Pipeline transform that looks up or inserts flag combinations (Hop Combination Lookup with EDW surrogate/hash options). Dimensional Update generates this transform for junk dimension tables; you can also place it by hand.
Options
-
Connection / schema / table — Junk dimension target.
-
Keys — Incoming flag fields.
-
Technical key — Surrogate column written to the stream.
-
Hash code — Optional combination hash strategy.
Prefer modelling the junk dimension on the .hdm canvas so DDL, catalog publish, and facts stay consistent.
