How to customize Commerce order admin view
In Drupal 7, Commerce 1 (7.x-1.x)

For the actual individual order page, you'll want to edit the view entitled &quot;Line items (Commerce Line Item)&quot;
Bear in mind however, the column you add may cause errors if the field only exists for some product types and not others. You might need to add an additional relationship to the view to get the field of data.

For the actual order summary page found at /admin/commerce/orders, you'll want to edit the &quot;Orders&quot; view.  You'll probably need to add a relationship for Commerce Order Line Items.
