Ora-06503/rep-1401 with my second report

Question

hello :D
im making my second report (new to reports, self studying)
i encountered REP-1401-'cf_itemtypeformula': Fatal PL/SQL error occured.
then i tried to trace the error by putting srw.message() in parts of the code to try to figure out the problem
here is cf_itemtype currently
function CF_itemtypeFormula return Char is
itype char(60);
begin
     srw.message(1000,'item type is'||:p_itemtype);
     --return ' ';
if :p_itemtype = '%-ALL' then
     itype:=' ';
     srw.message(1005,'itype code is'||itype);
     return itype;
else
     srw.message(1003,'item type is'||:p_itemtype); --it prints this one
     itype:='AND il.itty_code= itty.code and itty.item_type = '''||:p_itemtype||''' ';
     --itype:=' ';
     srw.message(1005,'itype code is'||itype); --and never reaches this line i think.
     return itype;
end if;
exception
     when value_error then
          srw.message(1007,'value error');
end;
i think the error is because of this line
'AND il.itty_code= itty.code and itty.item_type = '''||:p_itemtype||''' '
because when i comment it out and uncomment itype:=' '; the srw.message(1005,'itype code is'||itype); works
thanks

Hi,
You just need to increase the length of itype.
Or even better option is to return the value directly without assigning to a local variable.
return ('AND il.itty_code= itty.code and itty.item_type = '''||:p_itemtype||''' ');Your over all function without the SRW messages will be like, you don't even need Exception handler:
function CF_itemtypeFormula return Char is
begin
if :p_itemtype = '%-ALL' then
  return (' ');
else
  retrun ('AND il.itty_code= itty.code and itty.item_type = '''||:p_itemtype||''' ');
end if;
end;Also I have doubt about your if statement, I dont understand what you are trying to do by this.
> if :p_itemtype = '%-ALL' then
May be you just need to check if :p_itemtype is null
so may be your above IF clause will be like
> if :p_itemtype IS NULL then
