Group Step 

A Group step groups the individual steps or threads within the group box, and allows either any one of them to be executed, or all of them to be executed in sequence or in parallel. Any number of steps or threads may appear within a Groupstep, which has one (1) input and one (1) output. Its properties are listed in the table below.

Property	Description
Name	The step name.
Description	The step description.
Execution Type	The type of execution: ·        All Concurrent ·        All Sequential Random ·        Any Single

The step types that are valid within a Group step include: Process, Group, Connect, and Notify.

A Group step eliminates the complexity of typical flow diagrams, since a Group has just a single input and a single output.

Use the Group step if you want the parallel threads to be recombined into a single job, thereby allowing continued execution of the workflow to wait until all of the parallel threads have completed.
