Activity Markers
You can select BPMN Activity Markers on the Properties of the activity. The currently selected Activity Marker is indicated by a symbol on the activity.
- Multiple Instance Loop with Parallel Ordering
Indicates a task or sub-process activity that is replicated a fixed number of times based on the evaluation of an expression. The ordering is parallel.
- Multiple Instance Loop with Sequential Ordering
Indicates a task or sub-process activity that is replicated a fixed number of times based on the evaluation of an expression. The ordering is sequential.
- Standard Loop
Indicates a task or sub-process activity that might have more than one instance, depending on the conditions of the loop. A standard loop consists of a Boolean expression that is evaluated before or after each cycle of the loop. If the expression evaluates to True, the loop continues.
The conditions of the loop are set on the Loops tab (for more information, see Loops).
- Ad-hoc
Indicates an embedded sub-process that contains activities that have no predefined sequence. This also means that the number of times the activities are repeated is completely determined by the performers of the activities and cannot be defined beforehand.
Note: Script-tasks and many types of Service-tasks are not able to physically run in parallel. If it is important to your application to run multiple instances in parallel then you can refactor the task as a sub-process using the context menu. The sub-process invocation task can then be configured to be parallel multi-instance execution.
