For example, you have a Normalizer transformation that normalizes incoming quarterly sales data. You create the normalized field Y with an occurs value of 4.

In the Normalizer transformation, you configure the following field mapping:

Incoming field	Normalized field
Q1	Y_1
Q2	Y_2
Q3	Y_3
Q4	Y_4

The normalized field Y is then passed to the downstream transformation.

On the

Incoming Fields

tab of the downstream transformation, you get the lineage for field Y. Because fields Q1, Q2, Q3, and Q4 are mapped to occurrences of Y, they are included in the upstream lineage of Y.
