Pending noitifications query

Question

Hi there,
scenario: employee submits absences request through self service and manager receives notification. We would like to send a reminder to manager to approve the notifiation afer a certain period.
We have this query to fetch the notifications waiting for approval.
But there are few absences (HRSSA) transactions that are not picked up by this query and the reason is for those transactions there is no record in hr_api_transactions. but the notifications exist in wf_item_activity_statuses and managers can see the notifications on their home pages.
Can someone look at this query and explain why some absences have row in hr_api_transactions and some does not have. Please note that the absence type etc are all same other than employees.
select distinct wias.assigned_user,fu.email_address,trunc(sysdate) today
from hr_api_transactions hat
,hr_api_transaction_steps hats
     ,wf_item_activity_statuses wias
     ,fnd_user fu
where hat.transaction_id = hats.transaction_id
and hat.status = 'Y'
and wias.item_type = hats.item_type
and wias.item_key = hats.item_key
and wias.end_date is null
and wias.activity_status = 'NOTIFIED'
and wias.due_date is not null
and wias.assigned_user = fu.user_name
and mod((trunc(sysdate)-trunc(wias.begin_date)),3) = 0
ORDER BY email_address
Appreciate your time!
Many Thanks

I think you probably want to look at wf_notifications as that's the table that actually holds what notifications have been sent.
I haven't spent ages on this SQL so it's probably got holes but perhaps it might look something like this:
  SELECT   wfn.notification_id
          ,nvl(wfn.more_info_role, wfn.recipient_role) wf_role
          ,nvl(wfr2.display_name, wfr.display_name) wf_name
          ,nvl(wfr2.email_address, wfr.email_address) wf_email
          ,wfn.begin_date notif_sent_datetime
  FROM     wf_notifications wfn
          ,wf_roles wfr
          ,wf_roles wfr2
          ,wf_item_activity_statuses wfas
          ,hr_api_transaction_steps hats
  WHERE    wfn.status = 'OPEN'
  AND      wfn.recipient_role = wfr.name
  AND      wfn.more_info_role = wfr2.name(+)
  AND      wfn.item_key = hats.item_key
  AND      wfn.notification_id = wfas.notification_id
  AND      wfn.item_key = wfas.item_key
  AND      wfas.item_type = hats.item_type
  AND      wfas.due_date IS NOT NULL
  AND      wfas.end_date IS NULL;
