title: Pentaho Data integration transformation, Internal.Transformation.Filename.Directory not set
body: <p>I'm trying to use the built-in <code>Internal.Transformation.Filename.Directory</code> variable. I take as an example a simple sample the Pentaho Data Integration provides,<code>CSV Input - Reading customer data with error logging.ktr</code>.</p>
  
  <p>Here is the tooltip after CTRL+SPACE in a variable aware field:</p>
  
  <p><img src="https://i.stack.imgur.com/LUAhr.png" alt="Correct variable value"></p>
  
  <p>However I do exactly the same as in the sample my variable has no value:</p>
  
  <p><img src="https://i.stack.imgur.com/w9I2i.png" alt="Missing variable value"></p>
  
  <p>Any ideias? I've briefly checked Pentaho forum however the only related issue I found does not seem to answer my question.</p>
  
  <p>I'm using Ubuntu and PDI version 4.2.1.</p>
  
  <p>Thanks in advance.</p>
