Source reference
Overview
The Source reference page maintains relationships between two source objects before they are imported or transformed.
Function
Use Source 1, Source 2, Cardinality, Join, and Description to define the relationship between source objects.
The Reference Statement and Alias fields describe how the relationship is expressed.
The column mapping grid connects source columns or statements on each side of the relationship, and the inheritance options control whether metadata is inherited by default, blocked, or forced.
Access
Open an existing source reference from a source's References branch or from the Source references list.
