REP-1401: 'cf_10formula': Fatal PL/SQL error occurred. ORA-06502: PL/SQL: numeric or value error

Question

Hi Team,
I am running one conc programme.
After running I am getting below  error. I checked the issue on metalink  and other, seems that it is an size related issue. I have increased the size of formula columns and placeholdder too.
But still getting issue.
My requirement is to get comma seperated values using SQL query itself. Neither i wanted to create layout of the report , since it is a XML publisher report and nor  I am including it on RTF template.
I want the CF_10 formula column to be populated with comma seperated values.
MSG-00187: From Date 01-Sep-2014
REP-1401: 'cf_10formula': Fatal PL/SQL error occurred.
ORA-06502: PL/SQL: numeric or value error
And Here is my code for CF_10
function CF_10Formula return Number is
begin
   SELECT NVL(TO_CHAR(sum(Amount),'99,99,99,999'),0) into :CP_5 --NVL(ROUND(sum(Amount)),0) into :CP_5
--  xxhw_Coll_cat(category)     "Intercat  Catg"
FROM hhxw_Region_col_v
WHERE Category IN ('Intercompany - CATV')
AND trunc(gl_date) BETWEEN TO_DATE(:P_FROM_DATE, 'DD/MM/RRRR') AND TO_DATE(:P_TO_DATE, 'DD/MM/RRRR');
RETURN ROUND(:CP_5);
end;
Anyone please suggest me.

Hi,
1)Why are you selecting the value into a report item? Select into a local variable and return that
RETURN :CP_5 --> This one!!
2)And you should avoid applying functions to DB columns in where clauses wherever possible, so oracle can use indexes on them if applicable:
AND gl_date >= To_date(:P_FROM_DATE, 'DD/MM/RRRR')
AND gl_date < To_date( :P_TO_DATE, 'DD/MM/RRRR') + 1;
I think you are taking 2 column in the Layout CF_10 and CP_5 right? if so, then use below Query.
FUNCTION cf_10formula
  RETURN NUMBER
IS
  v_amount NUMBER:null;
IS
BEGIN
  BEGIN
    SELECT nvl(round(SUM(amount)), 0)
    INTO   v_amount --> Retruns the value for CF_10 column
    FROM   hhxw_region_col_v
    WHERE  category IN ( 'Intercompany - CATV' )
    AND    gl_date >= to_date(:P_FROM_DATE, 'DD/MM/RRRR')
    AND    gl_date < to_date( :P_TO_DATE, 'DD/MM/RRRR') + 1;
    :CP_5 := nvl(trunc(v_amount),0); --> Retruns the value for CP_5 column
  EXCEPTION
  WHEN OTHERS THEN
    v_amount := 0;
    srw.message(1003,'Error in Getting  :' ||p_from_date);
  END;
END;
And
If you've got a number function returning into a number field then all you should need to do to make the comma appear is to change the number format mask in field.
