title: How to Get the Data from Navigation Property of OData Service
body: <p>We are creating the Master Details UI5 app. I am calling the OData service and able to display the data from an entity set in Master list. On detail section, we are creating a form and I want to display the data which is coming from Navigation entity set. As I came to know that we can not call navigation entity set in a single call, how can it be done?</p>
  
  <pre><code>&lt;EntityType Name="Product" sap:content-version="1"&gt;
      &lt;Key&gt;
          &lt;PropertyRef Name="ProductID"/&gt;
      &lt;/Key&gt;
      &lt;Property Name="ProductID" Type="Edm.String" Nullable="false" MaxLength="10" sap:label="Product ID" sap:updatable="false"/&gt;
      &lt;Property Name="TypeCode" Type="Edm.String" Nullable="false" MaxLength="2" sap:label="Type Code"/&gt;
      &lt;NavigationProperty Name="ToSalesOrderLineItems" Relationship="GWSAMPLE_BASIC.Assoc_Product_SalesOrderLineItems" FromRole="FromRole_Assoc_Product_SalesOrderLineItems" ToRole="ToRole_Assoc_Product_SalesOrderLineItems"/&gt;
      &lt;NavigationProperty Name="ToSupplier" Relationship="GWSAMPLE_BASIC.Assoc_BusinessPartner_Products" FromRole="ToRole_Assoc_BusinessPartner_Products" ToRole="FromRole_Assoc_BusinessPartner_Products"/&gt;
  &lt;/EntityType&gt; 
  </code></pre>
  
  <p>I would like to show the data of <code>ToSupplier</code>.</p>
