title: overload of session log in informatica
body: <p>I have a mappig to update certain columns in a table. Only 10% or less records should get updated. The remaining records should be rejected by the informatica. </p>
  
  <p>The mapping works just fine if not for all the records getting logged into the session log file. Is there a way to prevent this other than using the filter transformation? I am aware this can be eliminated with a filter transforamtion. But just wanted to check if there is any simpler approach like selecting an option or something.</p>
