Need help me in usage of below given functions when MOAC set

Question

Hi,
Can somebody help me in answering for the below questions?
In R12, I set MO:Security profile at responsibility level and the profile has three OUs. Please see the below code.
declare
v_orgid1 NUMBER;
v_orgid2 NUMBER;
v_orgid3 NUMBER;
v_orgid4 NUMBER;
v_orgid5 NUMBER;
l_count NUMBER;
l_ou_cnt NUMBER;
v_user_id varchar2(100);
v_resp_id varchar2(100);
v_resp_appl_id varchar2(100);
begin
l_ou_cnt := mo_global.get_ou_count;
fnd_profile.get('USER_ID', v_user_id);
fnd_profile.get('RESP_ID', v_resp_id);
fnd_profile.get('RESP_APPL_ID', v_resp_appl_id);
fnd_global.apps_initialize(v_user_id, v_resp_id, v_resp_appl_id);
MO_GLOBAL.INIT('PO');
mo_global.set_policy_context('M',NULL);
v_orgid1 := mo_global.get_current_org_id;
FND_PROFILE.GET('ORG_ID', v_orgid2);
v_orgid3 := FND_GLOBAL.ORG_ID;
v_orgid4 := FND_PROFILE.VALUE('ORG_ID');
v_orgid5 := po_moac_utils_pvt.get_current_org_id;
SELECT count(1)
into l_count
FROM PO_HEADERS
WHERE EXISTS (SELECT 1 FROM mo_glob_org_access_tmp oa WHERE oa.organization_id = org_id);
end;
Qns:
1. FND_GLOBAL.ORG_IDFND_PROFILE.GET, FND_PROFILE.VALUE, PO_MOAC_UTILS_PVT, MO_GLOBAL functions are not returning org_id when mo security profile is initialized. the functions are returing -1 or NULL some times. Is there any specific function in R12 to return ORG_ID, if same functions when to use?(the functions are working fine when mo global is intialized for single org)
2. Irrespctive to where clause, the select statment is returning count of records for all mo security profile enabled orgs. Then why should not I get the records directly from ALL tables by using same where clause? Is there any specific reason in using Synoniams (poheaders, ....like)?
3. Can somebody explain usage of mo_global.get_current_org_id, po_moac_utils_pvt.get_current_org_id? If getting only for org_id in which case should i use both?
Appreciate your help !!!
Thanks
