PO- Recommunicated - Need to find who has done that

Question

Hi Team,
I am having one interesting question on PO email communication to supplier.
I have a PO which was created , shipped, invoiced and closed in March-2012, but unfortunately some body from business users re-communicated the PO to supplier again on 2nd-May-2012 , and the supplier sent the goods again. So now we are trying to find which business user has re-communicated the PO?
Verified the data in below wf tables but no clue.
select * from wf_notifications where notification_id = 79252394;
select * from wf_item_activity_statuses where item_key like '1029422%';
select * from wf_items where item_key like '1029422%';
PO Re-communication steps.
PurchaseOrder Summary > Query with PO Number > Tools > Communicate > Select Emaila check box and enter Email and Press ok.
Thanks,
Suresh

Hi Mahendra,
First of all thanks for your reply.
I have verified the query you given, but it din't returned any data. Also I don't see any concurrent program getting triggered after re-communicating the PO.
Just fyi..
I have done some further investigation below but ended up with no solution.
Step 1: Reproduced the issue in dev environment by enabling the SQL Trace, so that all sql statements (insert and update) will be captured.
Step 2: What is happening in the flow is, the resubmitting process will just make an entry in wf_notifications table and leaves it (request will be in pending status).
Step 3: We have every 5 min scheduled Work flow Background Process is place, which will process all pending notifications.
Step 4: So waited till next workflow background process completes to process my notification.
Step 5: So now I have the sql trace of both My action Plan + Workflow Background Process.
Step 6: From the SQL trace, the entire process touching below tables..
select * from wf_notifications where notification_id = 79252394;
select * from wf_item_activity_statuses where item_key = '1106292-18189';
select * from wf_items where item_key = '1106292-18189'
select * from WF_NOTIFICATION_ATTRIBUTES where notification_id=79252394
select * From WF_COMMENTS where notification_id=79252394
select * from FND_SEARCHABLE_CHANGE_LOG where pk_value_1=79252394
select * from WF_COMMENTS where notification_id=79252394;
select * from WF_ITEM_ACTIVITY_STATUSES where notification_id=79252394;
select printed_date,print_count, p.*
from po_headers_all p where po_header_id=1106292 (Here these 2 columns printed_date,print_count, will get updated)
But none of the table capturing the user information.
