OBIEE Write Back - Updating Multiple tables.

Question

Hi,
I am currenty using OBIEE writeback. Basically, I would like to make changes to 2 tables with a click of the writeback button. I create a function which updates both tables, and called the function in the xml page.
My page looks like this (I am only interested in updates as there will always be values in the relevant fileds):
<?xml version="1.0" encoding="utf-8" ?>
<WebMessageTables xmlns:sawm="com.siebel.analytics.web/message/v1">
<WebMessageTable lang="en-us" system="WriteBack" table="Messages">
<WebMessage name="DayDimWriteBack">
<XML>
<writeBack connectionPool="PRMI Admin Connection Pool">
<insert> </insert>
<update>SELECT f_dq_writeback('@{c8}',TO_DATE('@{c4}','YYYY-MM-DD'),'@{c2}','@{c9}') FROM DUAL</update>
     </writeBack>
</XML>
</WebMessage>
</WebMessageTable>
</WebMessageTables>
My function is:
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
create or replace function f_dq_writeback (i_reportable_flag varchar2,
i_date date,
i_username varchar2,
i_comments varchar2)
return varchar2
is
pragma autonomous_transaction;
lv_return varchar2 (1);
begin
update wh_day_dim
set cort_reportable_flag = i_reportable_flag
where day_date = i_date;
commit;
insert into dq_audit (username,creation_date,comments, as_at_date)
values (i_username,sysdate,'CORT_REPORTABLE_FLAG set to '|| i_reportable_flag|| '.'|| i_comments,i_date);
commit;
return lv_return;
exception
when others
then
lv_return := 'N';
raise_application_error (-20011,'Error occured during DQ Writeback: ' || sqlerrm );
end f_dq_writeback;
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
This just inserts into one table and updates another based on the parameters in the report.
However, it seems to act inconsistently when run, with results ranging from working fully i.e. amending both tables to amending one to not making any changes at all. The session log clearly shows that it is calling the function, but the results suggest otherwise. :

Am I doing something wrong or Is there any other way I can amend 2 tables using writeback.
Thanks
