Oracle Alert and sql query

Question

Hello, I am working on an oracle alert for PO's.
goal- when a PO is not approved/rejected by the approver and is waiting on approver's queue for more than 3 business days, an email should be sent to the approver every day saying "PO waiting for +xx+ days".
Working on R:12.1.1
Here is the script I could write and get emails of all unattended PO's. I am not able to use the dates.
Please help me out. Here is my script.
SELECT distinct poh.segment1,
TO_CHAR(SUM((pll.quantity - pll.quantity_cancelled) *
pll.price_override),
'$99999990.90'),
he.full_name,
NVL(fu1.email_address, '[email protected]') approver,
NVL(he.email_address, '[email protected]') owner,
pv.vendor_name,
vd.name
INTO &PO_NO,
&PO_AMT,
&CREATED_BY,
&APPROVER_EMAIL,
&CREATOR_EMAIL,
&VENDOR,
&DB_NAME
from wf_item_activity_statuses wias,
wf_notifications wfn,
po_headers_all poh,
po_line_locations_all pll,
fnd_user fu1,
fnd_user fu2,
hr_employees he,
ap_suppliers pv,
v$database vd
where wias.notification_id is not null
and wias.notification_id = wfn.group_id
AND poh.last_updated_by = fu2.user_id
and wfn.recipient_role = fu1.user_name
AND fu2.employee_id = he.employee_id
AND pll.po_header_id = poh.po_header_id
AND poh.vendor_id = pv.vendor_id
AND poh.type_lookup_code IN ('STANDARD', 'PLANNED')
and wfn.status = 'OPEN'
and wias.item_type = 'POAPPRV'
and wias.item_key = poh.wf_item_key
and poh.org_id = 81
AND poh.type_lookup_code IN ('STANDARD', 'PLANNED')
and poh.authorization_status IN ('IN PROCESS', 'PRE-APPROVED')
Thanks

Hi Sree,
