## Converting 3 steps table to only one table

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],
)```

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],
)``````

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.
