Validation Transform In BODS

Question

Hi All,
I'm trying to use the validation transform in BODS. The scenario is:
I have declared a variable $Product having value 'Oil','Gas','Fuel'
when I use the validation product IN ($Product) the validation fails even for the valid product entries.
But when I tried with giving the range of values directly instead of through variable like product IN ('Oil','Gas','Fuel') it works fine.
I'm in need of using it through the variable only..Any work around?? Please help....
Thanks and Regards,
Prateek

Prateek, please try this and let me know if this helps u..
Create a custom function (say Get_Match_Status) which accepts two parameters viz. the column value and the list of values (Oil, Gas and Fuel, in ur case). This should return 0 if the column value doesnt match with any of the list values. Otherwise it should return 1. Add a new column (Match_Status) to your query transformation (just before the validation transform) and call this function by passing the column 'Product' as the first argument and the variable '$Product' as the second argument - Get_Match_Status(Product,$Product). In the validation transform you can check the value of the column - Match_Status (this can be either 1 or 0)
Function body:
$Flag = 0;
while(length($In_Compare_Text )>0)
begin
     $Break_Text = word_ext( $In_Compare_Text ,1,',');
     if($Break_Text = $In_Text)
     begin
          $Flag = 1;
     end
     $In_Compare_Text = substr($In_Compare_Text ,index($In_Compare_Text,',',1)+1,length($In_Compare_Text)-index($In_Compare_Text,',',1));
end
if($Flag = 1)
begin
     return 1;     
end
else
begin
     return 0;     
end
Need to create two input parameters:
$In_Compare_Text   varchar   4000
$In_Text        varchar   30
Create two variables also:
$Break_Text    varchar     30
$Flag      int;
The return parameter has to be of type int
