SKIP_TRANSFORMATION records

Hi,

Is there a way to capture the records discarded by SKIP_TRANSFORMATION in Modified Javascript Step?

My Javascript code looks as follows:

//Script here
trans_Status=CONTINUE_TRANSFORMATION;
if(value == null || value.length == '')
{
trans_Status=SKIP_TRANSFORMATION;
}

I want to capture the bad rows in a file. Is there a way out?

Regards,
Bishnu
