Performing Impact Analysis on a Generated Transformation
Problem
You want to determine how many jobs are impacted by a change to a generated transformation.
A generated transformation is a transformation that you create with the Transformation Generator wizard. You can use this wizard to create your own generated transformations and
register them on a metadata server. After they are registered, your transformations display in the Transformations tree,
where they are available for use in any job. For more information about these transformations, see Creating and Using a Generated Transformation.
When you change or update a generated transformation, the change can affect the jobs
that include that transformation. Before you change
a generated transformation, you should run impact analysis on that transformation to see all of the jobs that might be affected by the change.
Tasks

Perform the following steps to run an impact analysis on a generated transformation:
-
Alternatively, you can select the object in a tree view or in the context of a process flow, and then select Actions from the menu bar, and then select Analyze. The following display shows the tree view of the analysis.
In the preceding display, the selected generated transformation is named Summary Statistics.
The Impact Analysis window shows that the selected transformation is used in the job Summary Statistics.
You can right-click
the objects on the Impact Analysis tab to
obtain information about those objects.
