How to access an added table column

I have added a column to a table in my canvas app.  This table is a query from a Dataverse table.  I want to access that new table column so that I can count the number of records that contain a certain value.  This is what I have:


AddColumns(Region,"Provinces",Text(ThisRecord.'Province'),"ProvinceCount",CountIf(Region,Provinces = "Alberta")


What is the correct syntax to get the count?

Count, CountA, CountIf, and CountRows functions in Power Apps

Also make a note of the following:

You need to enable the Enhanced delegation for Microsoft Dataverse option in the advance settings to make CountIf and CountRows functions delegation to work. To enable the option:

  1. Open the app where you want to use the functions.

  2. Select Settings > Upcoming features > Preview.

  3. Turn on the Enhanced delegation for Microsoft Dataverse option.


  • There is a 50K delegation limit if you use CountRows and CountIf functions with filters. There is no hard limit on the CountRows function when extracted directly from the data source because of the cached count that Dataverse keeps.
  • If the CountRows(<Data Source>) function is used without filtering, the count might not be 100% accurate, because the cached count updates periodically. If you need precise count and expect the result to be under the aggregate limit, you can bypass the cached count via CountIf(<Data Source>, True).


Essentially, the caveats stated above mean something like this:


1. There is a reference to a limit of 50,000 Records when using CountRows with any Filters, this is because 50,000 is the maximum number of records that can be returned by the underlying implementation when querying against Dataverse in that specific way.


2. If using CountRows on, for example, a whole Dataverse table directly, such as like this: CountRows(myDataverseTable), then there is "no limit", - however, there's a catch -  note that the underlying implementation may be using a cached count that is updating periodically - so there may be cases where the actual count returned may not be exact at the moment of calling this function. In some cases, this is fine. In other cases, this may not be desirable.


3. You can use CountIf(myDataverseTable,true) to get a more exact count and bypass the cached count. However, note that doing this will also trigger the 50,000 Record limit, so if there are more than 50,000 Records when calling CountIf(myDataverseTable,true), it will always return the number 50,000 in that case. 


See if it helps @z_mike_90 

Hi @z_mike_90 ,


Please try:

AddColumns(AddColumns(Region,"Provinces",Text(ThisRecord.'Province')),"ProvinceCount",CountIf(AddColumns(Region,"Provinces",Text(ThisRecord.'Province')),Provinces = "Alberta")


Best Regards,


Thanks for sending this.  The Enhanced delegation for Microsoft Dataverse option was enabled before I created this.  Also, there is much less than 50,000 rows (25) to be evaluated.

Thanks for sending this.  I copied your nested function (I also added the paren at the end) and get the error messages: "The function 'AddColumns' has some invalid arguments" and "The specified column is not accessible in this context" when I hover over the CountIf function.


Also, in the CountIf function, you have ThisRecord.'Province'.  Wouldn't the scope be only to one record?  I want to get a count of all the records in my table that have Province = "Alberta".

Hi @z_mike_90 ,


What type of column is your "Province" column in the data source "Region"?


Best Regards,



Hi @z_mike_90 ,


Is this a radio column?
In my test my "province" column is single selected.
Can you give me some examples?
Since I don't know your table structure, my test may not be what you want.







Best Regards,


The Dataverse column is a Choice column.
