Using variable in repository OBIEE

Question

Hi all,
This is my initialization string of physical table (select typ) in repository (hardcoded) :
SELECT * FROM TABLE(ORACLEBI.PKG_CASH_LIMITS.fn_b2export(2,2012)) I have two repository variables: aquarter and ayear. How do I set variables instead of hardcoded values?
Tried
SELECT * FROM TABLE(ORACLEBI.PKG_CASH_LIMITS.fn_b2export('valueof(aquarter)','valueof(ayear)')) and it gives no error, but also this query doesn't return any data.
Upd: yes, default values for repository variables aquarter and ayear are set (but still no result)

Well, the question is resolved for this moment. Honestly I don't like it, but it works. I've created view with nested pipelined function:
create or replace view oraclebi.vcash_limits as
with quarts as
select 1 as q from dual union all
select 2 as q from dual union all
select 3 as q from dual union all
select 4 as q from dual
years as
select extract(year from sysdate) r 
from dual
union all
select extract(year from sysdate) - 1 r 
from dual
union all
select extract(year from sysdate) - 2 r 
from dual 
prompts as (
select quarts.q, years.r from quarts, years
tsql as (
SELECT t.q, t.r, d.* FROM prompts t,
TABLE(ORACLEBI.PKG_CASH_LIMITS.FN_B2EXPORT(t.q,t.r)) d/*(+)*/
select * from tsql tand then filtered query result using OBIEE Analysis prompts on columns.
Thanks to all.
