    <p><strong>First</strong>, you're quoting the wrong example from table 151, page 366 of the PDF Reference document, because it doesn't match your case:</p> <pre><code>[page /XYZ left top zoom] </code></pre> <p>The real example which matches your case is:</p> <pre><code>[page /FitR left bottom right top] </code></pre> <p>meaning:</p> <blockquote> <p>Display the page designated by page, with its contents magnified just enough to fit the rectangle specified by the coordinates left, bottom, right, and top entirely within the window both horizontally and vertically. If the required horizontal and vertical magnification factors are different, use the smaller of the two, centering the rectangle within the window in the other dimension.</p> </blockquote> <p>because your case is quoted as:</p> <pre><code>[3 0 R /FitR –4 399 199 533] </code></pre> <p>Now, what the example refers to as <code>page</code>, in your case becomes <code>3 0 R</code>. The latter is a <em>reference</em> to object number 3 (generation 0) which you can find by searching your PDF for <code>3 0 obj</code>. This is the place that defines object number 3, which should name what your looked-for <code>page</code> for your <em>destination</em> is.</p> <hr> <p><strong>Update:</strong> If your real document indeed does contain the snippet <code>[3 0 R /FitR –4 399 199 533]</code>, then the same document should also contain another part which defines the page object (indirectly referred to) as <code>3 0 obj</code>. This part defines the page object and could read like this:</p> <pre><code> 3 0 obj &lt;&lt; /Type /Page /Parent 11 0 R /MediaBox [ 0 0 597.6 842.4 ] /Contents 31 0 R /Group &lt;&lt; /Type /Group /S /Transparency /CS /DeviceRGB &gt;&gt; /Resources 23 0 R &gt;&gt; endobj </code></pre> <p>Note, how this object again does refer to three other objects: <code>11 0 R</code>, <code>31 0 R</code> and <code>23 0 R</code>. The latter two point to objects 31 and 23, which hold the page's contents (31) and the resources (23), f.e. fonts, used by it. The first one points to the parent object (11) of this page.</p> <p>Note 2: The numbering of objects does not need to be sequentially as objects appear in the PDF file. The (almost) only condition is that the numbering is uniq.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
