GP_ABS_EVENT status fields

Hello Community,

I have a report where I want to show future absence events that are submitted, and indicated whether they are approved. I'm looking at 3 fields in GP_ABS_EVENT: Voided indicator, Manager Appr ind, and WF_Status. I would exclude any voided absences. So now I look at combinations of Manager Appr and WF Status and in my table I see:

Manager Appr Ind WF Status

N S (submitted)

Y blank (AM administrator approved, no workflow)

Y A (approved)

Y S (submitted)

What's the difference between the two Submitted WF statuses? Why is one Manager Approved and one Not Manager Approved? Is the Submitted with Yes Manager Approved truly considered approved? Or is there a better way to determine submitted and approved?
