title: Importing associated products and upsells using a Csv
body: <p>I am having a tough time finding a way to add associated products and upsells to my magento site.
  I found a template from another webpage stating the .csv should look like this :</p>
  
  <pre><code>sku---links_upsell_sku---links_related_sku
  </code></pre>
  
  <p>I use the --- as a way to show the different cells.</p>
  
  <p>I have tried using this, haven't met any errors in the dataflow import, but the products do not appear to have actually been added to the sku. </p>
  
  <p>I'm just wondering if anyone has managed to nail the process I am discussing?</p>
