DAX measure for percentage share

Anonymous — Wed, 07 Aug 2024 07:34:10 GMT

Hi together,

I have a simple example where I need to calculate the percentage share based on different aggregation levels but I don't know how to do this with a DAX Measure.
The data looks like this:

The first table in the top is the initial data. In one location is a division, for example manufacturing, and has a certain number of employees.
I would like to calculate
1. The percentage of employees for each division and each location (see left table)

2. The percentage of employees for all divisions at all locations (see right table)

Could any one tell me, how to write this within a DAX-Measure?

Thank you in advance.

Regards,

Andreas

Hi,

I am not sure how your semantic model looks like, but I tried to create a sample pbix file like below.

Please check the below picture and the attached pbix file.

share: = VAR _employee = [employee:] RETURN SWITCH ( TRUE (), ISINSCOPE ( location[location] ) && ISINSCOPE ( division[division] ) || ISINSCOPE ( location[location] ), DIVIDE ( _employee, CALCULATE ( [employee:], ALL ( division[division] ) ) ), DIVIDE ( _employee, CALCULATE ( [employee:], ALL () ) ) )

Hi Jihwan_Kim ,

thank you for your support. I have the same data model as you provided.

It's almost working.

Unfortunately I have the use-case that I need to pre-filter the report for some specific user groups.

So the table location has the column country inside and there is the prefilter on:

So the issue with that is that the 100 % level is shifting, depending on the filtered country.

Is there a way how to consider this filter within the measures? (So that each filtered country is considered as 100 %)

Thanks again.

Regards,

Andreas

Hi,

Thank you very much for your message, and I am not sure where the country is coming from.

Perhaps, you can try to replace ALL with ALLSELECTED DAX function.

ALLSELECTED function (DAX) - DAX | Microsoft Learn

share: = VAR _employee = [employee:] RETURN SWITCH ( TRUE (), ISINSCOPE ( location[location] ) && ISINSCOPE ( division[division] ) || ISINSCOPE ( location[location] ), DIVIDE ( _employee, CALCULATE ( [employee:], ALLSELECTED ( division[division] ) ) ), DIVIDE ( _employee, CALCULATE ( [employee:], ALLSELECTED () ) ) )

Hi, Anonymous

Thanks for Jihwan_Kim's concern about this issue.

His idea of a solution that I agree with.

I'd like to ask:

What exactly does your semantic model look like?

What are your form fields like? What kind of results are you looking for in the end?

I added the Country field and a few rows of data to the dataset based on the solution provided by Jihwan_Kim, but I'm not sure if it's consistent with the structure of your dataset:

Perhaps you need to create another new Measure to perform the calculations:

share1 = VAR _employee = [employee:] RETURN SWITCH ( TRUE (), ISINSCOPE ( location[location] ) && ISINSCOPE ( division[division] ), DIVIDE ( _employee, CALCULATE ( [employee:], ALLSELECTED ( division[division] ) ) ), ISINSCOPE ( location[location] ), DIVIDE ( _employee, CALCULATE ( [employee:], ALLSELECTED ( location[location] ) ) ), DIVIDE ( _employee, CALCULATE ( [employee:], ALLSELECTED () ) ) )

Choose a different Measure in a different visual, here is my test result:

If the above one can't help you get the desired result, please provide some sample data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. Thank you.

I hope my suggestions give you good ideas, if you have any more questions, please clarify in a follow-up reply.
