title: How to learn SAP ERP (without buying it)?
body: <p>I would like to learn SAP ERP. Is there a SAP ERP student edition?</p>
  
  <p>How do people practice SAP ERP? By trial version?</p>
  
  <p>If there is no way to download a free/trial, is learning Ofbiz useful to work in the future with SAP?</p>
