title: How to enable field in Acumatica - Sales Order with "shipping" status?
body: <p>I need custom field that I added to Sales Order screen to be always enabled even order has been shipped, order having "Shipping" status.
  I have extended SOOrder_RowSelected method to enable the custom field but the field is still disabled when the order is in "Shipping" status.</p>
  
  <pre><code>public class SOOrderEntryExt : PXGraphExtension&lt;SOOrderEntry&gt;
  {
      public virtual void SOOrder_RowSelected(PXCache cache, PXRowSelectedEventArgs e, PXRowSelected del)
      {
          SOOrder row = e.Row as SOOrder;
          if (row == null)
              return;
  
          if (del != null)
              del(cache, e);
  
         PXUIFieldAttribute.SetEnabled&lt;SOOrderExt.usrContact&gt;(cache, null, true);
      }
  }
  </code></pre>
