Power BI Masterclass - Advanced DAX - Which Product was Ordered First by Each Customer

The video tutorial covers creating a DAX measure to find the first product ordered by customers. It begins with setting up the style and proceeds to create a table displaying customer data. The tutorial explains using count distinct for order IDs and constructing virtual tables with the summarize function. Finally, it demonstrates the DAX calculation to identify the first product ordered, providing insights into customer data.

What is the main objective of the DAX measure created in the video?

• To determine the most frequently ordered product

• To calculate the average order value

• To identify the first product ordered by each customer

• To find the total sales for each customer

Why is it important to use 'count distinct' for order IDs?

• To find the maximum order value

• To calculate the average number of orders

• To avoid counting duplicate order IDs for the same customer

• To count the total number of products ordered

Which function is used to create a virtual table in DAX?

• CALCULATE

• SUMMARIZE

• FILTER

• SUM

What is the purpose of using the MAXX function in the DAX measure?

• To find the minimum value in a column

• To return the largest value from an expression for each row

• To calculate the sum of all values

• To filter out null values

How does the SUMMARIZE function help in creating a virtual table?

• It filters the data based on a condition

• It groups the data and creates a virtual table for calculations

• It calculates the average of a column

• It sorts the data in descending order

What is the significance of sorting the virtual table by the minimum date?

• To filter out duplicate products

• To calculate the total number of orders

• To find the most recent product ordered

• To ensure the earliest product ordered is at the top

What does the virtual table created in the DAX measure contain?

• Only the product names

• Only the order dates

• Both the product names and order dates

• Customer names and order IDs
