Using AGGR in a chart

Mon, 25 Jun 2012 15:35:59 GMT

Hi,

In order to calculate a Revenue in a chart, i thought i need to perform 2 steps:

=Sum(aggr(Sum($(Rev)),Campaign_ID))

Let say the $(Rev) is a variable with an expression that depends on the Campaign ID for its calculation.

So, I used the aggr(Sum($(Rev)),Campaign_ID) to calculate correctly the revenue per Campaign ID,

and then i used the external Sum() so the calculated revenue will be split according to the chart dimension.

But it doesn't work.

For Example, when i use this table this expression will work:

Date	Campaign	Revenue
21/6/12	1	250$
22/6/12	2	100$
23/6/12	3	55$

But when i use only the Date dimension in the chart, it will not work:

Date	Revenue
21/6/12	405$
22/6/12	0$

How can i make the expression works fine regardless of the dimension i choose?

Thanks,

Guy

Hi,

Use,

=Sum(aggr(Sum($(Rev)),Campaign_ID, Date))

=Sum(aggr(Sum($(Rev)),Date, Campaign_ID))

I need more info. A campain has... how many dates?

Do different campains have the same date?

luck

Hi Guy Davidovich,

Please correct me if i'm wrong.

You are using aggr(sum(expression),diimension) to calculate revenue. & on above that you are using sum on this aggr result.

If you are doing so, may be you are approaching in a wrong way cause you are trying to use arthematic function on a arthematic function. which may not work for ur case. Can you give a try to use total function.

hope this helps & correct me if i'm wrong.

thank you

Hi,

The Problem of using the expression

=Sum(aggr(Sum($(Rev)),Campaign_ID, Date))

is that is limited to Date as a dimension, and i using different dimensions (i let the user choose the dimension he likes, i think it called "flexing dimensions").

So, if the user choose another dimension to be shown in the chart, say Region, it will not work.

Any new suggestion?

Thanks,

Guy

Hi Guy,

As it's not limited to dimnsion, If you let user choose a dimension dynamically, It changes your aggregate value

but the dimensionalities which you are using in aggr functions have must contain your chart dimension. you can ask user to select a dimension but the dimensions which you are using in chart have to be there in aggr function & by choosing dimension dynamically it chnages your aggr value.

Hope this helps

thank you

Hi:

There is a funcktion

GetCurrentField(YourGroup) ///The QV color-sintax algrithm DOES NOT WORK HERE. Don't worry, it does it.

sum(aggr(Field,<YourGroup>)) ///I don't know if this one works fine

Think that aggregating is not easy. Try to do it with months and weeks. It will split both of them wrongly.

I managed to do this by using expression similar to this one:

='Sum(Aggr(Sum(PixelSum),$(=Concat(_dimension,',')&',Campaign_ID')))'

The $(=Concat(_dimension,',')&',Campaign_ID' build a string consists of the fields the user chose + Campaign_ID, so the AGGR will take place with consideration of the dimensions of the charts, and still make the calculation for each Campaign.

Thanks A lot for helping ,e get the solution!
