display values with a specific condition

[ali_hijazi]

Hello got the following sample data
Payment ID    Payment Source    Payment Amount
1                         Source 1                     500
1                         Source 1                     400
1                         Source 2                     900
2                         Source 1                     100
2                         Source 2                      50

I want to calculate the variance of each Payment ID between Source 1 and Source 2
Variance is:
Sum({< [Payment Source] = {"Source 1"}>} Payment Amount) - Sum({< [Payment Source] = {"Source 2"}>} Payment Amount) 

Now what I want to display on a Table Chart the payments that got a variance = 0
so in this table I want to display only Payment ID 1

kindly advise on how to accomplish this

Hello,

You can use something similar to this expression:

Sum(Aggr(Sum({<[Payment Source]={"Source 1"}>}[Payment Amount]), [Payment Source], [Payment ID]))

The dataset looks like this:

Then you can create a Table chart with [Payment ID] dimension and the expression above as measure, which will give you an output:

As you can see the ID 1 is 0 and ID 2 is 50. So you can go a step further, by adding the expression in an If() statement to display the value of ID if it is 0 or Null() and it will remove all the rows that are not 0.

I hope that this information was helpful. In case I have misunderstood the use case scenario, please elaborate in details by providing additional information.

If I understood your requirement correctly, you want to show payments where the balance is null. You can use your expression as a measure, but you will need a calculated dimension to show only the payments with balance is null.

You can use this as a calculated dimension (use the expression editor for this field)

=Aggr(If(Sum({< [Payment Source] = {"Source 1"}>} [Payment Amount]) - Sum({< [Payment Source] = {"Source 2"}>} [Payment Amount]) =0,[Payment ID]),[Payment ID])

Now you only have to untick the box 'Null-values'

Kind regards

Eddie

Hello
I managed to do the following; the thing is I only want to display a dimension i.e. without a measure
aggr(only
(
{
<[Payment ID]={
"=sum(aggr(Sum({<[Payment Source] = {[Source1]}>}[Payment Amount]) - Sum({<[Payment Source] = {[Source2]}>}[Payment Amount]),[Payment ID])) = 0"}
>
}[Payment ID]),[Payment ID])

Ok, you have two options here.

1. Calculate this in the loadscript (allways better)

2. Use the calculation as calculated dimension and for the measure (you'll need it anyway) you fill in =1 and then for conditional show you fill in 0. See example (is Dutch)
