Hi @minseon ,

To sum sales from 2 years ago 1st of month to end of this month, you can use the following DAX formula:

``````Sales 2 Years Ago =
CALCULATE(
SUM('Transaction Table'[Sales Amount]),
DATESBETWEEN(
'Calendar'[Date],
DATE(YEAR(SELECTEDVALUE('Calendar'[Date]))-2, MONTH(SELECTEDVALUE('Calendar'[Date])), 1),
LASTDATE(DATE(YEAR(SELECTEDVALUE('Calendar'[Date]))-2, MONTH(SELECTEDVALUE('Calendar'[Date])), 1))
)
``````

This formula calculates the sum of sales amount from the transaction table between the first day of the month two years ago and the last day of the month two years ago based on the date slicer selection.

If it does not help, please provide more details with your desired output and pbix file without privacy information (or some sample data) .

I can provide you with a general idea that you can adapt to your situation.

Assuming you have a date column in your transaction table and you're using a tool like Microsoft Excel, Power BI, or a similar tool, here's a general approach using DAX (Data Analysis Expressions) language:

Let's assume your transaction table is named Sales and has a column Date representing the transaction date.

1. Create a Date Table: Make sure you have a separate calendar table with a continuous range of dates that covers the entire period of your sales data.

2. Create a Relationship: Ensure there's a relationship between the Date column in the Sales table and the corresponding date column in your calendar table.

3. Create a Measure: Create a new measure that calculates the sum of sales for the selected range. In DAX, it might look something like this:

SalesSum = CALCULATE(SUM(Sales[SalesAmount]),
FILTER(ALL('Calendar'),
'Calendar'[Date] >= MIN('Calendar'[Date]) &&
'Calendar'[Date] <= MAX('Calendar'[Date]) &&
'Calendar'[Year] = YEAR(TODAY()) - 2 &&
'Calendar'[Month] = SELECTEDVALUE('Calendar'[Month])
)
)

1. In this example, YEAR(TODAY()) - 2 calculates the year two years ago, and SELECTEDVALUE('Calendar'[Month]) gets the selected month from the slicer.

2. Use the Measure in Your Report: Drag the SalesSum measure into your report, and it should dynamically aggregate the sales based on the selected slicer values.

Remember to adjust the table and column names based on your actual data model.

If you provide more details about the specific tool you're using, I can give you a more tailored solution.
