title: Blue Prism : Need help to update a collection
body: <p>This has been driving me nuts for ages now and I know it might seem really basic but I don't remember it ever being covered in the training course I'm taking. Basically I have built a process that logs in to an order system, gets items from a work queue, places an order and then captures the reference number. </p>
  
  <p>The reference number I am sending back from the <code>capture reference</code> Business Object to the Process but I am stumped as to how to add this data to my existing collection as the column name does not exist. 
  I keep getting the error </p>
  
  <blockquote>
    <p>Field Data.reference-number not found</p>
  </blockquote>
  
  <p>and I know this is because it doesn't exist in the Current Values tab in the collection. </p>
  
  <p>The best I can do is store this returning data into a separate data object in order to not disrupt the process but this doesn't really help me as I need to be able to view the reference number in the control room via the data logs of the work queue.</p>
  
  <p>Can anybody help me append this returning data to my existing collection? Would really appreciate the advice. Thanks </p>
