Bex Query Condition

Hi ,

I have created a query with Top N condition .There are total 7 conditions and input value for N is derived from selection screen using a formulae variable.

In this case i have entered input values in two variables "Damage Count" and "Object part count" and value is 10 (It can be seen in screenshot).

After getting default out put i activate 1st condition and below is my output. As expected i get 10 rows for top 10 Damage Count.

Now when i activate another condition on "Object count "the output gets restricted to 7 rows only.

I was expecting Top 10 Damage and object count but i get random 7 rows when both the conditions are active. I don't understand this behaviour.The result should be intersection of two conditions right? Pls let me know if i am missing something.

Thanks
