linked one dataTable to the rows of another

Hello !

Here is my situation:

Imagine a table in Excel "Gestion" with several records. Each of the records have a country and an amount:

CountryAmount

France

100
Allemagne100
Suede100
France5
France10
Suede50
Allemagne25
France100

 

 

In my DataTable on the app, there is a column indicating the countries. I want to make a 2nd column in my DataTable allowing the sum of all the amounts whose country is France (here 215).

Result in the application:

France - 215

Germany - 125

Sweden - 150

So I created a second DataTable with this function: 

 

AddColumns ( Gestion; "Expenses"; Sum ( Filter ( Gestion; 'Country' = ???? ); 'Amount' ) )

 

 But I don't know what to put in ?????

I would like to select the 1st row of the country column then 2nd ...

I hope it's possible.

Thanks in advance !

@taubry ,

This is not gone like you, but the formula removes any threats of delegations warning. 

Is a formula for behavioral properties (Like OnSelect) and the result will be a collection with 2 columns (Country and SumPerCountry) called CountryCentralizedResult (lack of idea).

 

 Also, you'll notice that is a time consumer as you filter the Excel table for each country (more countries more time):

With(
    {
        distinctCountry: GroupBy(
            Table1,
            "Country",
            "Result"
        )
    },
    Collect(
        CountryCentralizedResults,
        ForAll(
            distinctCountry As currentCountry,
            With(
                {
                    currentCountryData: Filter(
                        Table1,
                        Country = currentCountry.Country
                    )
                },
                {
                    Country: currentCountry.Country,
                    SumPerCountry: Sum(
                        currentCountryData,
                        Amount
                    )
                }
            )
        )
    )
)

 If your excel file did not exceed 500 rows,  there is another approach you can use directly in a non-behavioral property (like items):

With(
    {
        groupByCountries: GroupBy(
            Table1,
            "Country",
            "Result"
        )
    },
    AddColumns(
        groupByCountries,
        "SumPerCountry",
        Sum(
            Result,
            Amount
        )
    )
)

Hope it helps !

I specify that I tried with: 

AddColumns ( Gestion; "Expenses"; Sum ( Filter ( Gestion; 'Country' = DataTable.Selected.Gestion ); 'Amount' ) )

 This displays the correct result but only for the selected row. For example I clicked on the France line and on each line I had 215, even on the Germany line.

Hi @taubry 

Thanks for sending me a message about your post. Can you try @gabibalaban's suggestion to see if that works?
The additional comment I would make is that the Excel (OneDrive) connector doesn't support the retrieval of rows abover row 2000, so the second formula would offer a simpler solution.

@taubry ,

Yes it is possible and did not complicate the things at all, again with the  observation that it works only with 500 rows in your Excel file or 2000 rows as @timl said if you change the maximum retrievable rows in PowerApps app. 

With(
    {
        groupByCountries: GroupBy(
            Table1,
            "Country","City","Year",
            "Result"
        )
    },
    AddColumns(
        groupByCountries,
        "SumPerCountry",
        Sum(
            Result,
            Amount
        )
    )
)

 

Thanks it works! I made the second solution.

Yes, sorry it's quite simple, I misspoke my question. I would like to be able to filter and select the results only for 2021.
