  <pre><code>Item (name, note, storedItem)
  StoredItem (price, item)
  Item 1 ---&gt; N StoredITem (1-&gt;N Relationship)
  </code></pre>
  
  <p>I want that Item has a fetched property named minPrice and its value is the minimum value setted for price in the storedItems.</p>
  
  <p>Example:</p>
  
  <pre><code>Item1 (banana, storedItem1 ... storedItem4, 10)
  StoredItem1 (10,item1)
  StoredItem2 (15,item1)
  StoredItem3 (30,item1)
  StoredItem4 (54,item1)
  </code></pre>
  
  <p>What do I put in Destination?? StoredItem?</p>
