Mass transitions
You may need to trigger several transitions simultaneously, that is to pass several workflow instances from one status to another.
To be able to authorize transition mass triggering:

In the properties dialog box of a workflow transition, select the value "Yes" in the
Mass Transition field.
When the workflow is instanced, you can trigger mass transition from:
• subject objects
• workflow instances
To trigger a transition simultaneously on several workflow subjects in the same current status:

Right-click the subject objects, for example in a navigation tree, and select command
Mass Transition.

The instances must be in the same workflow status to enable a mass transition.
