<p>In our last few <a href="http://www.gozync.com" target="_blank">GoZync</a> deployments we’ve noticed folks frequently need to pull some related data down to the mobile file, but don’t want (or need) to sync the whole related table. Let’s say you want to get a customer’s credit limit on your iPhone but don’t want to sync the (massive) invoices table that is needed to calculate it. </p>

<p>Well now GoZync will let you pull that field with a <a href="http://www.seedcode.com/pmwiki/pmwiki.php?n=GoZync3.CalcFields" target="_blank">simple mod</a>. This made several very cool use cases a real snap to sync. So keep in it mind for your next project.</p>
