Sage HR Workflow Recipient Type

I have to make adjustments to some HR Workflows, but most are set up using these new option. And I can’t make changes until I know what the current process is doing. The first 2 are standard, and I know what they do, but the next 3 I don’t know.

 

I can probably figure out option 3 and 4, but 5 is the one I have the real problem with.  There is no help on this, and no manual either....
