title: Incorrect SUM in HANA Calculation Graphical View
body: <p>I am trying to do a Sum of quantity for products, using HANA Calculation Graphical View.</p>
  
  <pre><code>MATNR | MENGE
  
  AAA | 1
  
  AAA | 2
  
  AAA | 2
  
  BBB | 2
  
  BBB | 3
  </code></pre>
  
  <p>Using aggregation node, I choose MATNR as normal output and MENGE at Aggregated Output.</p>
  
  <p>The result is, MATNR AAA always shows 3 which is not correct (BBB is 5, correct). </p>
  
  <p>I tried set the source view to CUBE, change MATNR to attribute (and make it KEY field), also change MENGE to measure. Every suggestion I have read but no luck. </p>
  
  <p>I understand that aggregation node auto groups the same value before Sum. How do I avoid it and get correct result for MATNR AAA?</p>
  
  <p>Thank you</p>
