Purge Conflicts
In purging, a conflict is an exception condition with known resolution or resolutions. Purge uses the conflict framework to report problems that can be overridden in execution and possible resolutions.
In particular, purge allows you to preselect an override for the following conflicts:
Downloaded to a workspace
Shared to a project
* 
If a task fails with an exception, it cannot be retried.
