REP-1241 Circular column dependency originating with column

Question

Dear,
I receive the error,
REP-1241 Circular column dependency originating with column 'cenvat_opening'
I have the following return statement for a column total_credit;
function total_creditFormula return Number is
begin
Return (return nvl(:cf_cenvat_closing ,0) - nvl(:cf_duty_on_goods_ed,0);
end;
Now i am using this total_creditFormula for the error formula column 'cenvat_opening'
function cenvat_openingFormula return Number is
f_num_opn number(14,2);
begin
SELECT NVL(Amount,0) INTO F_NUM_OPN
FROM Fin_Ex_Pla_Debit_Others
WHERE FISCAL_YR_CD = :P_FISCAL_YR
AND PERIOD_NO = :P_PERIOD
AND ADD_TYPE = 'I';
RETURN(F_NUM_OPN);
EXCEPTION
     WHEN NO_DATA_FOUND THEN     
     RETURN (:total_credit); <------------
end;
here the formula column 'total_credit' has the following return statements;
RETURN Nvl(:cenvat_opening,0) + Nvl(:cenvat_credit_manu,0)
so how can i use this formula column? is there any other option to return the value in the same column.
I hope you understand,
Pls help,

Hi,
Iam presuming here that your report contains atleast 2 queries, with each requiring the other to be executed first. The query listed in the message is one of the conflicting queries.
You may want to edit the query listed or another conflicting query to remove the circular dependency.
