I’m sorry if this has somehow slipped through the cracks, but would it be possible for us to open a ticket with you so you can invite our support user into your workspace? This way we can easily see how to build this to your desired results. 

Please, you can solve problem with “previous”.

Thank you.

 

Hi, but that's not the right idea because you don't know what the last month's dates are. THIS" macro I can't use, because macro solve current month.

Perhaps I misunderstood the issue here. Could you please try this metric and let us know if this helps? 

SELECT COUNT (id_licence) WHERE Month/Year (Date_from_licence) = THIS -1

The above metric will show you values for only the previous Month only. In the above metric I am incorporating the "THIS"macro, and more details on this can be found here:

The same result.

Hello, 

from the screenshot of your metric we can see that you're using the date attribute "Month (Date_from_licence)".  Can you please try and update your metric so it uses the date attribute "Month/Year (Date_from_licence)" instead? Once you use this date attribute it will then look for the values for the previous Month/Year. Could you please give this a try and let us know if this helps?

You may need to utilize a primary key when using the COUNT Function

 

SELECT COUNT(attribute, primary_key)

or

SELECT COUNT(attribute) USING primary_key

Would it be possible to share a screenshot of your LDM?

Hello,

Yes, I use date filter on Dashboard without problem.

You are very welcome.

The metric looks just fine to me. Please, are you using the Month Date filter on your Dashboard as well?

Also, this might be related to your Logical Data Model itself. Dates are usually uploaded as the standalone datasets, also known as Date Dimensions. You can find more information here.
 

Thank you for help, but I did not right result for my metric.

 

I created metric:

SELECT COUNT(id_table_a) FOR PREVIOUS (Month/Year (a_date)).  

I got all rows without filter .   Where is problem ?

Hello,

What seems to be an issue here, please? I assume that you are working with our Insights and KPI Dashboards, but please correct me if I am wrong.

You can work with FOR PREVIOUS clause directly in your measure or you can use the KPI Dashboard Date filter, concretely the Predefined period for the Last month.
