Monthly Portfolio Reporting

 Calculate Sales last day of each month

Problem Scenario: Monthly Portfolio Reporting

Background: You work as a financial analyst at a large investment firm. Your team is responsible for analyzing the performance of various investment portfolios on a monthly basis. Each portfolio consists of a diverse range of assets including stocks, bonds, and mutual funds.

Problem Statement: Your team needs to generate monthly reports summarizing the performance of each investment portfolio. The reports should include key metrics such as total portfolio value, asset allocation, and performance returns. However, the challenge lies in identifying the latest available data for each month to ensure accurate reporting.

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 evaluated. It allows you to apply filters and manipulate context within expressions.
MAX Function:
MAX is a DAX function that returns the maximum value in a column. In this case, it's applied to the 'Date' column within the 'Sales' table.
ALLEXCEPT Function:
ALLEXCEPT is a table manipulation function that removes all filters from a table except those you specify. In this case, it retains the filter context for the 'Month' column while removing filters from other columns in the 'Sales' table.
Function Explanation:
The "Lastdateineachmonth" DAX function calculates the maximum ('MAX') value of the 'Date' column within the 'Sales' table, considering only the context defined by the 'Month' column. The ALLEXCEPT function removes all filters from the 'Sales' table except for the 'Month' column. This ensures that the MAX function operates within the context of each month independently.
Practical Application:
This function is particularly useful in scenarios where you need to identify the last date of each month within a dataset. It can be applied in financial reporting, sales analysis, and various other domains where monthly summaries or reporting intervals are critical.
For instance, in financial analysis, you might use this function to identify the latest available data for each month, facilitating month-end reporting and analysis.
By utilizing the "Lastdateineachmonth" DAX function, you can streamline your data analysis processes and extract valuable insights with precision and efficiency.

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...
