title: multiple level of expansion in crm webapi
body: <p>I have an entity called as medicalcase</p>
  
  <p>Each medical case has a subgrid, N:N relationship with an entity called as mcfamily</p>
  
  <p>Each mcfamily has Father, Mother, Child fields which are lookups to contact field</p>
  
  <p>Now if I make a webapi call </p>
  
  <pre><code>http://serverurl/api/data/v8.0/new_medicalcase(caseid)?$expand=new_medcase_mcfamily
  </code></pre>
  
  <p>I get the new_father_value, but I want to expand the Father lookup and get the contact name. How can I do it?</p>
  
  <p>I tried</p>
  
  <pre><code>http://serverurl/api/data/v8.0/new_medicalcase(caseid)?$expand=new_medcase_mcfamily($expand=new_father($select=fullname))
  </code></pre>
  
  <p>But it said </p>
  
  <blockquote>
    <p>navigation property can't be expanded. Multiple levels of expansion
    aren't supported.</p>
