Could not update list of Fields for the query in SSRS

While Connecting to the stored procedure from the SSRS reports getting below error.

"Could not create a list of fields for the query. Verify that you can connect to the data source and that your query syntax is correct."

An item with the same key has already been added.

I have added here sample stored procedure created.

create procedure products
as
begin
    with #ProductCat as(
        select DPC.EnglishProductCategoryName,DPC.FrenchProductCategoryName,dpsc.EnglishProductSubcategoryName,DPSC.FrenchProductSubcategoryName
        from DimProductCategory DPC
        join DimProductSubcategory DPSC on DPC.ProductCategoryKey=DPSC.ProductCategoryKey
    )
select PC.EnglishProductCategoryName as Product_Category,PC.FrenchProductCategoryName as Product_Category
,PC.EnglishProductSubcategoryName as Product_SubCategory
from #ProductCat PC
end

Two column names are having in the output with same name.
unfortunately SSMS will not throw any error for this.
Make proper naming while naming the dataset column names.

Report Snapshots in SSRS

·         A report snapshot provides the ability to run a report at a scheduled time or on demand and save the report in the ReportServer database.

·         You can schedule report snapshots to be run during off-peak hours; this can reduce the load on your database servers

·         When select a report snapshot for viewing, the report server retrieves the stored report from the report server database and shows the data and layout that were current for the report at the time the snapshot was created.

·         Any data source used in the report must store the credentials for connecting to the database

·         Make sure SQL Server Agent is running.
