title: Hybris: add attributes to product via Impex
body: <p>I have a product catalog and a classification catalog. The product catalog contains a product and the classification catalog contains attributes, however when I try to insert the product with the attributes it doesn't show when I click the product and go under attributes tab.</p>
  
  <p>How I enter product with attributes:</p>
  
  <pre><code>$lang=en
  $productCatalog=productCatalog
  $catalogVersion=catalogversion(catalog(id[default=$productCatalog]),version[default='Staged'])[unique=true,default=$productCatalog:Staged]
  $approved=approvalstatus(code)[default='check']
  $baseProduct=baseProduct(code,$catalogVersion)
  $clAttrModifiers=system='MySystemClassifications',version='General',translator=de.hybris.platform.catalog.jalo.classification.impex.ClassificationAttributeTranslator,lang=nl
  $id=@id[$clAttrModifiers];
  
  
  INSERT_UPDATE Product;code[unique=true];$id;$catalogVersion
  ;M300047;200.59;
  </code></pre>
  
  <p>Is there something I have to do after adding it to link it to the product?</p>
