Answer / bidhar
In SCD 2 you must be generating the surrogate keys.
Example:
Customername Address Customer_id Customer_identifier
Amit Bangalore 100 10
Amit Hyderabad 100 11
Amit Pune 100 12
Amit Mumbai 100 13
Here column Customer_identifier is the surrogate key.
so for latest record ,you can pick up the record which have
maximum surrogate key value(13).
Let me know if i am wrong.

IN THREE WAYS WE CAN GET THE LATEST RECORD IN SCD ...
1)IN "SCD TYPE 2 TIME STAMP" FOR LATEST RECORD THE "END
DATE" FIELD WILL BE BLANK. THAT MEANS IT IS THE NEW ROW .
2)IN "SCD TYPE 2 FLAG " THE FLAG NUMBER OF THE NEW ROW WILL
BE ONE .
3) IN " SCD TYPE 2 VERSION " THE LATEST RECORD IS HAVING
THE MAXIMUM VERSION NUMBER .
