Refining an Impact and Lineage Analysis

When reviewing your analysis, you can refine it by removing or adding initial objects, changing the analysis rule sets to be used, and/or customizing actions. If you have generated an IAM, you can customize the display preferences and model options, print the model, and/or compare it with another IAM.

• Removing or Adding Initial Objects From/to the Analysis
  Change the focus of your analysis by removing or adding initial objects.
• Removing Collections of Influencing and Dependent Objects
  You can remove objects collections from the analysis to make it more readable.
• Changing the Analysis Rule Sets
  You can change the rule sets used to analyze your change to see it from a different point of view, by for example moving from a data impact analysis to a conceptual impact analysis.
• Customizing Actions
  The predicted effect on an object in the analysis is called an action. You can modify actions using the following commands available from the initial and dependent objects contextual menu in the preview or in the IAM:
• Printing the Analysis
  You can print out your analysis from the preview List tab or from the IAM or create an IAM list report in order to document and discuss your proposed changes.
• Comparing Two Analysis
  Since the IAM is a PowerDesigner model, you can compare the content of two IAMs in order to:
• Customizing the IAM Environment
  The IAM environment includes a set of parameters and configuration options that define various aspects of the model content and behavior.
• Understanding Cross-model Dependencies During the Analysis
  When you generate a model to another model or create an external shortcut, you create cross-model dependencies, which are taken into account during impact and lineage analysis.
