Dax Function: Lastdateineachmonth = CALCULATE( MAX('Sales'[Date]), ALLEXCEPT('Sales', 'Sales'[Month]) ) Dax Explanation: CALCULATE Function: CALCULATE is a powerful DAX function used for modifying the context in which other functions are ev...

 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...

Understanding DAX Week Number Calculation with Conditional Logic Dax:  Week_num =     IF(         'Date'[WeekDayName] in {"Sat", "Sun"},         BLANK(),         WEEKNUM('Date'[Date], 2) -         WEEKNUM(EOMONTH('Date'[Date], -1) + 1, 2) + 1     ) Explanation: In Power BI and other Microsoft data analysis tools, understanding date calculations is crucial for accurate reporting and visualization. One common requirement is to calculate week numbers, but often, we need to exclude weekends from the count. The provided DAX function accomplishes this task efficiently. Introduction: Date-based analysis often involves tracking data by week, but the definition of a week may vary depending on business requirements. This DAX function not only computes week numbers but also intelligently handles weekends, ensuring that week counts accurately reflect working days. Function Overview: The  We...

Time Intelligence Dax Functions - Power BI TOTALYTD: Calculates the year-to-date total for a given expression. Example:  Total Sales YTD = TOTALYTD(SUM('Sales'[Amount]), 'Date'[Date]) TOTALQTD: Calculates the quarter-to-date total for a given expression. Example:  Total Sales QTD = TOTALQTD(SUM('Sales'[Amount]), 'Date'[Date]) TOTALMTD: Calculates the month-to-date total for a given expression. Example:  Total Sales MTD = TOTALMTD(SUM('Sales'[Amount]), 'Date'[Date]) DATESYTD: Returns a table that contains all dates from the beginning of the year up to the specified date. Example: Sales YTD = CALCULATE(SUM('Sales'[Amount]), DATESYTD('Date'[Date])) DATESQTD: Returns a table that contains all dates from the beginning of the quarter up to the specified date. Example: Sales QTD = CALCULATE(SUM('Sales'[Amount]), DATESQTD('Date'[Date])) DATESMTD: Returns a table that contains all dates from the beginning of the mon...
