Before you can perform an impact analysis on artifacts,
you must first create an impact analysis profile.
About this task
Impact analysis diagrams are driven by impact analysis profiles.
Profiles can limit the linked artifacts that are included in an impact
analysis diagram. For example, a profile can specify the following
limitations:
- Restrict links to only upstream or downstream artifacts.
- Upstream links lead to the focus artifacts in an impact analysis.
- Downstream links lead away from the focus artifacts in an impact
analysis.
- Restrict the depth of each link followed.
- Restrict the kinds of links that are followed.
- Restrict the kinds of artifacts that are included in the diagram.
Procedure
- In the main menu, click .
- In the editor, click in the title field and type a unique
name for the new profile.
- To specify how the analysis traverses artifacts as it builds
the diagram:
- To include artifacts that are upstream from the focus
artifact, downstream from the focus artifact, or both, set the Traversal list
box.
To learn more about the upstream and downstream
settings, hover over the small question marks to read hover help.
You
might see artifacts in your analysis that you do not recognize, such
as Class and Architecture Resource.
The downstream and upstream impact analysis profiles that are shipped
follow all types of links to all types of artifacts in the index,
including the ones that determine each artifact's type. (The link
is abbreviated rdf:type, and labeled in diagrams
as type.) The rdf:type links lead
to artifacts that are labeled as Class in the navigation
tree, while oslc_am:Resource links lead to Architecture
Resource artifacts. If you see more artifacts that you do
not recognize, they are likely other links of this kind.
- Set the depth to control how many node levels you want
analyzed by entering a number in the depth field.
- Optional: Set a type for the analysis to
find by clicking the Set Depth Based on Type icon.
In the Select Type dialog box, set Value to
specify the artifact type. The artifact type that you set replaces
the depth, and the analysis searches until it finds the type.
- Set filters to control which artifacts and links the diagram
can show or ignore. Click the Add Filter icon
and then choose a default filter or a custom filter that was set up
for your team.
The new impact analysis profile is included
in the list of available profiles.
- Optional: Export the profile to another Rational® Engineering Lifecycle
Manager installation.
- In the main menu, click .
- Check the box beside the profile names that you want
to export.
- Click the Export Selected Profiles icon
to start the download.
Exporting profiles also exports
all Impact Analysis filters that are included in the selected profiles.

new impact analysis profile.
