title: Setting input parameter for a method
body: <p>I have an object called <code>X</code> with a method <code>GET_BANK</code>, like in the picture below:</p>
  
  <p><img src="https://i.stack.imgur.com/ijpz4.png" alt="enter image description here"></p>
  
  <p>I want to call the function <code>GET_BANK</code> and I am trying to set the input parameter <code>BLZ</code> with a certain value.</p>
  
  <p><strong>I don't quite understand the data structure that is presented here and how I can access it.</strong></p>
  
  <p>At this point my code looks like this (simple version):</p>
  
  <pre><code>data: testobj type ref to ZCO_BLZSERVICE_PORT_TYPE .
  data: input type ZGET_BANK .
  input-BLZ = '10070000'.
  </code></pre>
  
  <p>I think the error that I am getting "The data object "INPUT" does not have a component called "BLZ"." is not relevant as I obviously have no idea on how to set the BLZ parameter.</p>
  
  <p><strong>Edit:</strong> Getting to BLZ can be done by chaining multiple parameters / objects: </p>
  
  <p><code>input-PARAMETERS-BLZ = '10070000'.</code></p>
