title: SAPUI5 batch submit returns error
body: <p>I am using the following code, in an attempt to batch upload the changes made on a table:</p>
  
  <pre><code>onConfirmActionPressed: function() {
      var oModel = this.getModel();
  
      oModel.setUseBatch(true);
  
      oModel.submitChanges();
  }
  </code></pre>
  
  <p>I am using <code>setProperty()</code> to set the new values, like this:</p>
  
  <pre><code>onSingleSwitchChange: function(oControlEvent) {
      var oModel = this.getView().getModel();
      var rowBindingContext = oControlEvent.getSource().getBindingContext();
  
      oModel.setProperty(rowBindingContext.sPath + "/Zlspr", "A");
  }
  </code></pre>
  
  <p>When <code>onConfirmActionPressed</code> is executed, I get a server error, saying that "Commit work during changeset processing not allowed" on SAP R3.</p>
  
  <p>When I upload the lines of the table one-by-one, it works fine. However, uploading this way is very slow, and in some cases it takes more than 10 minutes for the process to complete.</p>
  
  <p>Am I doing something wrong while batch submitting? Is there a chance the issue is due to server (R3) misconfiguration?</p>
