Invoice Validation status check in Invoice base tables - urgent Pls..

Question

All,
Version:11.5.10.2
After the invoice is validated in Invoice workbench (AP), where the validation status got stored. I came across ap_invoices_v table and AP_INVOICES_PKG.GET_APPROVAL_STATUS package can be used to check the status. But I've seen in ap_invoice_distributions_all table, match_status_update flag gets updated with flag 'A' after validation of invoice.
I want to know which option(view,package or ap_invoice_distributions_all table) Oracle recommends to check the status of invoice.

Metalink note 301806.1 tells how the validation status is generated (it is not a field in a table for sure) which is different from approval_status.
I have taken the note and came up with this function to determine it and works well so far.
FUNCTION getvalstatus(p_invoice_id IN NUMBER) return VARCHAR2
IS
p_dist_count NUMBER;
p_dist_valid_count NUMBER;
p_dist_nevvald_count NUMBER;
p_dist_needs_revald NUMBER;
p_hold_count number;
p_status varchar2(25);
BEGIN
SELECT count(*) INTO p_dist_count FROM
ap_invoice_distributions_all WHERE invoice_id=p_invoice_id;
SELECT count(*) INTO p_dist_valid_count FROM
ap_invoice_distributions_all WHERE invoice_id=p_invoice_id
and match_status_flag='A' ;
SELECT count(*) INTO p_dist_nevvald_count FROM
ap_invoice_distributions_all WHERE invoice_id=p_invoice_id
AND (match_status_flag='N' OR match_status_flag IS NULL);
SELECT count(*) INTO p_hold_count FROM ap_holds_all
WHERE invoice_id=p_invoice_id
and release_lookup_code is null;
IF (p_dist_count=p_dist_valid_count and p_hold_count=0 and p_dist_count <>0) THEN
p_status:='Validated';
ELSIF
p_dist_count=p_dist_nevvald_count THEN
p_status:='Never Validated';
ELSIF
p_hold_count >0 THEN
p_status:='On Hold';
else
p_status:='Needs Revalidation';
end if;
RETURN p_status;
end getvalstatus;
