If Google is correct, there is no such thing as RFSTDTC in SAS.

Explain further what it is and what you are asking about.

@sharathbairoju The information you're looking for is CDISC related, not SAS specific, so although you may be lucky enough to find someone who knows the answer, this isn't likely the best place. I assume that CDISC and the FDA put out fairly detailed documentation about the requirements though.

I'm assuming you'll find that information here, but I can't be certain.
