Converting 3 steps table to only one table

Anonymous — Thu, 28 Oct 2021 14:52:35 GMT

Hi, I am new to DAX and I have an assignment which requires me to simplify all 3 steps table to only one table, preferably using CALCULATETABLE function.

Been trying this for almost 2 weeks now, still can't seem to get the idea.
Does anyone know how I can simplify these steps to only one table?

Thank you

Table 1:

forecasting_uoa_transactions_step1 = 
    FILTER (  
        SUMMARIZE ( 
            uoa_transactions_history, 
            uoa_transactions_history[Date], 
            uoa_transactions_history[Country], 
            "UoA", SUM(uoa_transactions_history[Total Changes])
        ),  
        DATEDIFF(uoa_transactions_history[Date],TODAY(),MONTH)<variable_uoa_per_cust_window[Variable_UoA_per_Cust_Window Value]+1
    )

Table 2:

forecasting_uoa_transactions_step2 = 
    SUMMARIZE ( 
        forecasting_uoa_transactions_step1, 
        forecasting_uoa_transactions_step1[Country],
        "UoA Per Customer Average", AVERAGE(forecasting_uoa_transactions_step1[UoA_per_Customer])
    )

Table 3:

forecasting_uoa_transactions_step3 = 
    SELECTCOLUMNS ( 
        customer_transactions_forecast,
        "Date", customer_transactions_forecast[YearMonth],
        "Country", customer_transactions_forecast[Country],
        "Customers", customer_transactions_forecast[Total Headcount]
    )

Table 3 seems to be unrelated to the first two steps. Please validate your request.

Hi,

According to your description and DAX formulas, I can roughly understand your requirement, I think you can use VAR to define the above two calculated tables as virtual tables to achieve the result in one single DAX formula, you can try to create a calculated table like this:

forecasting_uoa_transactions= VAR _step1 = FILTER ( SUMMARIZE ( uoa_transactions_history, uoa_transactions_history[Date], uoa_transactions_history[Country], "UoA", SUM(uoa_transactions_history[Total Changes]) ), DATEDIFF(uoa_transactions_history[Date],TODAY(),MONTH)<variable_uoa_per_cust_window[Variable_UoA_per_Cust_Window Value]+1 ) VAR _step2 = SUMMARIZE ( _step1, [Country], "UoA Per Customer Average", AVERAGE( [UoA_per_Customer]) ) RETURN SELECTCOLUMNS ( _step2, "Date", [YearMonth], "Country", [Country], "Customers", [Total Headcount] )

And you can get what you want.

If this result is not what you want, you can post some sample data(without sensitive data) and your expected result.
