Sum with dimensions and sub dimensions

Hi,

If i set a bar chart with the dimension Q1 OP and the following metric:

sum({$<Q1_VALUE={1}>} F) / sum(total {$<Q1_VALUE={1,0}>} F)

The values that are displayed are correct, split by Q1 OP. But the same chart with the dimension Q1 shows incorrect values. Shouldn't the chart with dimension Q1 display the same values as Q1 OP but added up?

Thanks.

Not entirely sure I understand... but may be you need this

Sum({$<Q1_VALUE={1}>} F) / Sum(TOTAL <Q1> {$<Q1_VALUE={1,0}>} F)

Hi, i've tried that and it makes no difference to the values presented. I've blanked out the names of the categories, but the chart on the left should add the values of the chart on the right.

Question, you have changed the dimension from Q1 OP to Q1 or are you just adding Q1 to Q1 OP? If you replaced, then may be try this

Sum(Aggr(Sum({$<Q1_VALUE={1}>} F) / Sum(TOTAL <Q1> {$<Q1_VALUE={1,0}>} F), Q1, [Q1 OP]))

Hi,

That's it, thanks for your help. If it's not much to ask, can you explain the logic behind your thinking ?

Basically, you were only showing Q1, but you really wanted to perform the calculation at the Q1 OP level and then add it up... So, in order to do that you can use Aggr() function... which create a virtual table where there are two dimensions Q1 and Q1 OP and perform the calculation with both dimensions. And later Sum() function just sums up all the values of all Q1 OP within the Q1.

Second part, was the TOTAL qualifier. Here we needed to add <Q1> because when you performed the calculation... it seems that you only had selected a single Q1.... which is why you saw the total for Q106_7. But if nothing was selected... it would have showed overall total... in order to make the total for each Q1, I added TOTAL <Q1>.

Perfect. Thank you again.
