Answer / sumit gupta

Whenever you update physical file, then it checks for all
file level keyword that specifies on logical file if any.
If no logical then simple update will perform.
In this, before updating your physical file temporary
program will get the UNIQUE specified as file level keyword
on 1 logical file.
