Changing the collections displayed beneath an object

Chapter 12 Impact Analysis

Changing the collections displayed beneath an object

You can add or remove the collections displayed beneath a selected object in order to narrow or widen the analysis.

To change the default collections of an object:

Right-click an object in the Dependencies tree, and select Change Propagation Collections from the contextual menu in order to open the Object Propagation Collections dialog box.

This dialog lists all the collections available for the object:

Select or deselect any of the following checkboxes in order to modify the display of one or more collections:
- S [Selected] - displays the corresponding collection under the object category in the Dependencies list
- L [Replace link object by extremity] - If the object is a link, hides the it to simplify the display and visualize only the link extremity
- R [Recursive] - displays recursive collections in a single list

[optional] Click the Edit Default Propagation Rules tool to open the Propagation Rules Definition dialog and associate additional collections with the object. For more information, see Creating a user-defined event.

Click OK to return to the Dependencies tab.

The collections appear under the selected object in the tree.

Adding user-defined collections
You can define your own collections of objects and display them in the Impact Analysis graph. For example, in a model where columns diverge from domains, if you create a calculated collection on the domain metaclass that lists all the columns that use the domain and have identical data type, it becomes much easier to evaluate the impact of a change on the domain. For more information, see the "Managing Profiles" chapter in the Advanced User Documentation .
