Impact Analysis Diagram

Go Up to ER/Studio Business Architect Tools

Once you have created a link or usage, you can create an Impact Analysis Diagram displaying a graphical representation of those links. You can update an existing Impact Analysis diagram rather than generating a new one for the same element. The Impact Analysis Diagram can also be viewed as a grid.

If a source object has been linked to an External Data Object Attribute, Column, or Data Element, they also will appear on the Impact Analysis Diagram. Their names are displayed as ParentName.Name in the view and are not editable in the diagram. You can double-click on them to open the associated Property View, where you can change their properties.

Right-click an element that you have created a link or usage for in the Model View tree and select Impact Analysis > Generate New Diagram....

OR

Select an element in the Model View tree or Diagram View and on the main menu select Tools > Generate Impact Analysis Diagram....
