title: Informatica - Duplicate elimination
body: <p>I am having a flat file with 10 records, and out of it 5 records are duplicate records (unique key column: <code>Customer_Id</code> and <code>source_system</code>). This flat file has to load to a Oracle table and this is the first load.</p>
  
  <p>How can I eliminate the duplicates in it?</p>
