Characteristic Values get aggregated along hierarchy

Hi,

I have a query containg testsuite(characteristic), duration(characteristic) and status(key figure). when Testsuite is displayed as hierarchy, values of duration for the childnode gets propagated to the parent node. Is there a way to avoid this.

Tst dur status

T1 10 pass

20 pass

T2 20 pass

In the example above T2 is a child of T1 and hence the value 20 can be seen for T1.

I have checked the values in the ods object. There is only one row corresponding to T1.

Thanks in advance
