Launching an Impact and Lineage Analysis

Analyze the impact of a change to your model from the Impact and Lineage Analysis dialog box.

The Impact and Lineage Analysis dialog lets you review your analysis through:

A preview – displays the impact and lineage analysis in a tree form (see PowerDesigner Core Features Guide > Reviewing an Analysis in Preview).
An impact analysis model (IAM) – displays the impact and lineage analysis in a diagram (see PowerDesigner Core Features Guide > Reviewing an Analysis in an IAM Model).

Open an impact and lineage analysis in any of these ways:
- Select an object in the Browser or in the diagram and press Ctrl + F11.
- Select one or more objects in the diagram and select Tools > Impact and Lineage Analysis.
- Right-click an object symbol in the diagram and select Edit > Impact and Lineage Analysis.
- Right-click an object entry in the Browser and select Impact and Lineage Analysis.
- (When deleting an object) Click Impact on the Confirm Deletion dialog box.
- Open an object's property sheet, click the Dependencies tab, then click Impact Analysis .
(Optional) Enter a name for your analysis result. This becomes the name of the generated model.
Select an impact rule set for your analysis. Choose one of these predefined rule sets:
- Conceptual Impact Analysis – restrict the analysis to objects impacted by modeling changes on the initial object, such as a modification on a requirement definition.
- Data Impact Analysis – identify the use, if any, of a value contained in the initial object.
- Delete Impact Analysis – (default when deleting an object) restrict the analysis to objects that are directly impacted by the deletion of the initial object.
- Global Impact Analysis – (default when not deleting an object) identify all the objects that depend on the initial object.
- None – no impact rule set is selected.
Select a lineage rule set for your analysis. Choose one of these predefined rule sets:
- Conceptual Lineage Analysis – justify the modeling existence of the initial object, and ensure it fulfills a well-identified need.
- Data Lineage Analysis – identify the origin of the value contained in the initial object.
- Global Lineage Analysis – (default when not deleting an object) identify all the objects that influence the initial object.
- None – (default when deleting an object) no lineage rule set is selected.
(Optional) Click the Properties tool next to each rule set to review it (see PowerDesigner Core Features Guide > Editing analysis rules).

The analysis appears in the Impact and Lineage tab of the dialog box (see PowerDesigner Core Features Guide > Reviewing an Analysis in Preview).

Note: You can click the Select Path tool to change the default folder for analysis rule sets, or click the List of Rule Sets tool to open the List of Impact and Lineage Analysis Rule Sets window, and review a specific rule.
