title: How to lock the aggregation level in a result
body: <p>I’m having a problem trying to lock the aggregation level in a result.</p>
  <p>I have a report showing : store, articule, sales, and stock. I need that the sales metric doesn’t change despite the store.</p>
  <p>For example: if one articule had 3 sales in one store and 2 sales in the other one, the report should show 5 sales no matter what store I am looking for.</p>
  <p>Do you have any suggestions?</p>
