title: Add extra fields openERP 7
body: <p>I need to add several extra fields to an existing openERP module, i red somewhere else that i need to do it through the menus</p>
  
  <blockquote>
    <p>First create the fields using Configuration -> Customization ->
    Database Structure -> Fields</p>
  </blockquote>
  
  <p>but i cant find that options or do i need to install something else so i have that functionality?</p>
  
  <p>I also checked under the admin the techincal features, but nothing.</p>
  
  <p>i have seen several post and other users directly add code 
  thanks!</p>
