Murali, think about what you are asking.  You are asking if you can take a
file that has duplicate keys and make it have unique keys.  Only one of two
options exist:

1. The operating system deletes records with duplicate keys
2. The operating system keeps the duplicate keys

Option one would destroy data.  I doubt this is what you want.  Option two
is a contradiction, because the keys in the file would not be unique.

So, common sense should indicate that the answer is no, you cannot convert a
file with duplicate keys to unique key access, without first removing the
duplicate keys.

If you choose to ignore common sense, you could simply try it yourself, like
I did, and find that you'll get a CF4012 if you try to access a unique view
over a file with duplicate keys.  I did this by entering data into a file,
then changing the file to UNIQUE.  When I went to access the file with
UPDDTA I could not access it.

On the other hand, I was able to access the data in this mangled file using
SQL.  So the answer to your problem might be simply to use SQL.
