title: populate the content of two files into a final file using pentaho(different fields)
body: <p>I have two files.
  file A has, 3 columns
  Sno,name,age,key,checkvalue</p>
  
  <p>file B has 3 columns
  Sno,title,age</p>
  
  <p>I want to merge these two into final file C which has
  Sno,name,age,key,checkvalue</p>
  
  <p>I tried renaming "title" to "name" and then I used "Add constants" to add the other two field.</p>
  
  <p>but, when i try to merge these, I get the below error</p>
  
  <p>"
  The name of field number 3 is not the same as in the first row received: you're mixing rows with different layout. Field [age  String] does not have the same name as field [age String].<br>
  "</p>
  
  <p>How to solve this issue.</p>
