If the entity is associated with multiple tables, you should use a version mapping only with the primary table. You should have only a single version mapping per persistent entity. Version mappings may be used only with the following attribute types:</p>
+<ul>
+<li>
+<p><code>int</code></p>
+</li>
+<li>
+<p><code>Integer</code></p>
+</li>
+<li>
+<p><code>short, Short</code></p>
+</li>
+<li>
+<p><code>long, Long</code></p>
+</li>
+<li>
+<p><code>Timestamp</code></p>
+</li>
+</ul>
+<p>To create a version mapping:</p>
+<ol>
+<li>
+<p>In the <a href="ref_persistence_outline.htm#BABEGGFE">JPA Structure view</a>, select the field to map.</p>
+</li>
+<li>
+<p>Right-click the field and then select <span class="bold">Map As &gt; Version</span>. The <a href="ref_persistence_map_view.htm#BABIFBAF">JPA Details view (for attributes)</a> displays the properties for the selected.</p>

+<p>Complete each field in the <a href="reference034.htm#CACHAEBB">Version Mapping</a> area.</p>
+</li>
