title: Reset sequence number monthly
body: <p>VL/11/2014/050 to VL/12/2014/001 </p>
  
  <pre><code>    &lt;record id="seq_new_lead" model="ir.sequence"&gt;
          &lt;field name="name"&gt;Visit Log&lt;/field&gt;
          &lt;field name="code"&gt;lead&lt;/field&gt;
          &lt;field name="prefix"&gt;VL/%(month)s/%(year)s/&lt;/field&gt;
          &lt;field name="interval number"&gt;1&lt;/field&gt;
          &lt;field name="interval units"&gt;months&lt;/field&gt;
          &lt;field name="padding"&gt;3&lt;/field&gt;
  
      &lt;/record&gt;
  </code></pre>
  
  <p>but it's not working. It should reset automatically at every month and start with 001.  </p>
