You can analyze the impact of a change to an object (impact analysis) and identify the objects that take part in the definition of the object (lineage analysis) on any model object in the repository by right-clicking it in the Repository tab of the Browser and selecting Impact and Lineage Analysis.
By default, the analysis descends to only three levels of dependencies, but you can select more or fewer levels by selecting a number in the Repository analysis level list.
For detailed information about using this dialog, see Impact and Lineage Analysis. For information about the limitations of repository analyses, see Repository Rule Set Limitations.
Note: By default, analyses launched from the Repository tab use the standard Global Impact Analysis and Global Lineage Analysis rule sets delivered with PowerDesigner and available in the Library folder. You can check additional rule sets into the library or into another repository folder (see Checking Rule Sets into the Repository). To change the folder where PowerDesigner looks for rule sets for selection in the dialog, use the Choose Path tool above the rule set fields.
