IS_VALID_DATE

Hi Gurus,

I want to capture Invalid dates.I am using IS_VALID_DATE function in validation transform to check whether the date is valid or not. For example if the Input filed FILE_DATE has invalid date value like 20111550 i would like to store that invalid value. How ever after using IS_VALID_DATE function in Validation transform the invalid date value is converted into blank. I want to capture the invalid values so that we know what is invalid. Any idea how to capture it.

Thanks in Advance,

Pan
