Last 12 Months from Today

 Last 12 Months from Today


Dax Formula:

Last12Months = 
IF (
    AND (
        'Calendar Table'[Date] >= EDATE(TODAY(), -11),
        'Calendar Table'[Date] <= TODAY()
    ),
    1,
    0
)

Explanation:
This function appears to be designed to create a flag or indicator for dates falling within the last 12 months relative to the current date.

Here's a breakdown of how the function works:

1) IF Statement:

The function starts with an IF statement, which evaluates a condition and returns one value if the condition is true, and another value if the condition is false.

2) AND Function:

Within the IF statement, there's an AND function, which checks if all of its arguments are true. In this case, it's checking two conditions.

3) EDATE Function:

The EDATE function is used to calculate a date that is a specified number of months before or after another date.
EDATE(TODAY(), -11) calculates the date that is 11 months before the current date (TODAY()).

4) Comparison:

The function compares the date in the 'Calendar Table' to see if it falls within the range from 11 months ago to the current date.
'Calendar Table'[Date] >= EDATE(TODAY(), -11) checks if the date is greater than or equal to 11 months ago.
'Calendar Table'[Date] <= TODAY() checks if the date is less than or equal to the current date.

5) Result:

If both conditions are true, meaning the date falls within the last 12 months, the function returns a value of 1.
If either condition is false, indicating that the date is outside the last 12 months, the function returns a value of 0.

In summary, the "Last12Months" function assigns a value of 1 to dates falling within the last 12 months relative to the current date, and a value of 0 to dates outside this range. This can be useful for filtering or aggregating data based on a rolling 12-month period.

Create Calendar Table in Power BI using DAX Function

 Calendar Table using Dax Syntax: CalendarTable = ADDCOLUMNS ( CALENDAR (DATE(2024, 1, 1), DATE(2024, 12, 31)), "Year", YEAR([Date]), "MonthNumber", MONTH([Date]), "MonthName", FORMAT([Date], "MMMM"), "Quarter", QUARTER([Date]), "DayOfWeek", WEEKDAY([Date]), "DayOfMonth", DAY([Date]), "WeekdayName", FORMAT([Date], "dddd"), "IsWeekend", IF( OR(WEEKDAY([Date]) = 1, WEEKDAY([Date]) = 7), TRUE(), FALSE()), "IsHoliday", IF( OR( MONTH([Date]) = 1 && DAY([Date]) = 1, MONTH([Date]) = 7 && DAY([Date]) = 4), TRUE(), FALSE()) ) Explanation: CALENDAR (DATE(2024, 1, 1), DATE(2024, 12, 31)) Creates a table with a single column containing dates from January 1, 2024, to December 31, 2024.

Calculate Sales for Last Year Month to date

Sameperiodlastyear till to date based on selection in year and month selection Problem:  If the current year and month are selected, sales data from the same period of the previous year up to the current date is needed. For instance, if it's March 2024, you'd require sales data from March 2023 up to today's date. If the selection is for a different year and month, such as January 2023, you need the entire sales data for January 2022. Solution:  For this scenario you need to create Three Dax Measures Measure 1 = (This measure is to calculate current month sales till the date) CALCULATE( SUM(CST[Total Financed Amount]), SAMEPERIODLASTYEAR( DATESYTD('Calendar Table'[Date]) ), FILTER( ALL('Calendar Table'), 'Calendar Table'[MonthNum] = MONTH(NOW()) && DAY('Calendar Table'[Date]) <= DAY(NOW()) ) ) Explanation: CALCULATE : This is a DAX function used to modify or filter the context for a calculation. It can apply additional filters to a ...

CONTAINSTRING DAX

Exploring the CONTAINSSTRING Function in DAX Understanding the CONTAINSSTRING Function At its core, the CONTAINSSTRING function enables users to determine whether a specific substring exists within a given text string. This function returns a Boolean value, TRUE if the substring is found, and FALSE if it is not. Here's the basic syntax of the CONTAINSSTRING function: CONTAINSSTRING(<text>, <substring>) <text>: The text string within which you want to search. <substring>: The substring you're searching for within the text. Practical Example: Using CONTAINSSTRING in DAX Let's delve into a practical example to grasp how the CONTAINSSTRING function works within the context of DAX. Suppose we have a dataset containing product information, including a column named ProductName. We're interested in identifying which product names contain the word "apple". We can achieve this by creating a calculated column using the CONTAINSSTRING functi...
