You can start a comparison between the design of any entity type, or the source code of Macros. You can perform a comparison in the history between two versions of an instance, or a comparison between two instances.
To start comparing, you must do the following actions:
This choice compares the two selected instances.
This choice compares the selected instance with one of its versions that are stored in the local history.
This choice opens the History view in comparison mode. Double-click one of the versions that are displayed in this view to start comparing it with the current version that is selected in the Design Explorer view.
This choice is available if you are connected to the Rational Team Concert™ server that stores the selected instances. It compares the selected instance with one of its versions that are stored on the server. In the Component source wizard that opens, you must indicate where the version can be found on the server.
This choice opens the History view in comparison mode. Double-click one of the versions that are displayed in this view to start comparing it with the current version that is selected in the Design Explorer view.
This choice is available if you are connected to the Rational Team Concert server that stores the selected instances. It compares the selected instance with its latest version that is stored on the server.
This choice opens the History view in comparison mode. Double-click one of the versions that are displayed in this view to start comparing it with the current version that is selected in the Design Explorer view.
This choice is available in the Pacbase facet, from a subordinate instance. A subordinate instance is an instance that has the same name as an instance in a higher project of the design build path hierarchy. The instance in the higher project is the master instance.
If this master instance is modified, you must decide to copy or to ignore these modifications in the subordinate instance. To copy the modifications, you must open the compare editor and manually copy some or all of the modifications.
