Table reference

Overview

The Table reference page maintains a relationship between two warehouse tables, including join behavior, inheritance, column mapping, and transformation usage.

Function

Use Cardinality, Join, Table 1, Table 2, Description, and Reference Statement to define the relationship.

Inheritance controls whether metadata is inherited by default, blocked, or forced, and Auto created and Inactive control how the relationship is managed.

The Columns grid maps the reference columns and the Used in transformations grid shows where the relationship is used.

Access

Open an existing table reference from a table's References branch or from the References list.

How to access

Layers -> [layer] -> [schema] -> Tables -> [table] -> References -> [reference] -> Edit table reference.

Toolbar

DWH -> References, then double-click a table reference row.
