I'm agree with naveen patil, Hashed file is used for lookup process. Beside that, Hashed file can also be used if we want to get Distinct data from a source by using the column as key. Sample, I want to get list of country from Customer records. One possible solution is I create a Hashed file and using Country as its key. Then I can get distinct value of Country.
