Report builder measure issue

Peter_23 — Wed, 08 Jan 2025 00:04:07 GMT

Hi community.

I work with report builder, this time is my first report in this tool, I trying to display a table with measures, but I don't make a correct calculation. I mean.

Country	City	stock	orders	Average
US	NY	100	30	0.0
US	LA	130	10	8.0

So I have on SM this dimensions: Country, City and measures : stock, orders, average.

the measure "average" is in fact, DIVIDE ( orders , stock ) so the correct values are: NY 30, LA 7,69, eg.

Average is not aggregate in report builder because it is calculated in formule [Average] meanwhile stock and orders are sum. OK

If I developmented this table in power bi report the measures are OK.

Is there anything is way wrong? Calculation, expression or something.

thanks in advance.

Hi, Peter_23

Based on the dimensions you showcased, I've made some example data:

Add this dataset in Report builder. Then insert a tablix:

Use the following expression:

IIf(Fields!Stock.Value<>0,Fields!Orders.Value/Fields!Stock.Value,0)

Set the display format:

Here are the results:

thanks Anonymous I have to use expression formule, but is it possible to use measure "averange"?

If I don't have group rows defined in the table (Country, city), the measure works, but I would like sumarrized values. 🙂

Country	City	Stock	Orders	Averange
US	NY	75	20	26.6
US	NY	25	10	40
US	LA	100	5	5
US	LA	30	5	16.6

So is there anyway to use measure instead of expression in group row?

thanks

Hi, Peter_23

If so, I recommend that you connect Power BI Report builder to your semantic model. Create a new summary table in your semantic model with DAX expressions:

Table = SUMMARIZE('SalesData','SalesData'[City],'SalesData'[Country],'SalesData'[Orders],SalesData[Stock],"Avuerage",DIVIDE('SalesData'[Orders],'SalesData'[Stock])*100)

Connect to your semantic model in Power BI Report builder:

Here, in addition to creating a calculated table in Power BI beforehand, you can also use measures from your semantic model.

Below is the generated DAX query. If you're good at it, you can write straight into Query Designer instead of going into it.

You don't even need to resort to a semantic model. If you have SSAS, you can connect directly to your data source there, then write the corresponding DAX expression, and finally connect it in Report builder.

You can only use expressions in Power BI Report builder, not measures (except in the case of connections to semantic models or SSAS).

If you still decide to use expressions, check out this article below to learn about the syntax of Report builder.

Thanks Anonymous thanks

The SM is actually in the service so the live connection is it.

When you said:

"You can only use expressions in Power BI Report builder, not measures (except in the case of connections to semantic models or SSAS)."

I could be use or could be not? (Measures)

Hi, Peter_23

Thank you very much for your reply. If you're connecting to a semantic model in the service in real time, you can use measure.

You need to write the relevant measure in your semantic model and then connect it.

Thanks Anonymous Yes, It is. but I trying to add grand total, so the sum(measure) don't have a correct value because it's division function, so which aggregation should be for grand total?

thanks in advance.

Hi, Peter_23

Based on your description, I created a tablix:

This results in the correct summing of the measures:

Anonymous thanks for example, the sum are OK. Orders =40 and Stock 230, the measure are incorrect 40 / 230 = 0.173913043 , not 0.376... (totals) is the same issue I'm having too.

Hi, Peter_23

Thank you very much for clarifying this. To do this, I changed my expression as follows:

Thanks again Anonymous Yes, you can use expression instead of measure defined.

I understand it's not possible to use measure aggregation to total when the measure is division, standard deviation , etc, I should be rewrite the formule in expression. This way I have many measures and expression as same functions as many reports or report builders.

I figure out as good practice use defined measure in SM.

So I'm going to use expression.

Hi, Peter_23

As you described, there are many duplications in expressions and measures. Since the total is added after loading the dataset into the report builder and then creating a new visual object, some expressions cannot be avoided.
I think this is because of two different products. At first, it was dedicated to paginated reports and served SQL Server Reporting Service. At that time, expressions were used, which was a long time ago. In recent years, it has developed into Power BI Report Server, which integrates Power BI's semantic model and other functions into it. This is also the current preview stage.
As recommended, complete the writing of measures in the semantic model as much as possible, and then present the data in Power BI Report Builder.
If you have already got the answer to the current problem in the previous reply, you can mark the corresponding reply as a solution so that other people in the community can quickly find help when they encounter similar problems.
