Power BI Masterclass - Learning DAX: Advanced Searching in Power BI

This video tutorial guides viewers through the process of performing an advanced search using DAX in Power BI. It begins with importing data into Excel, followed by visualizing and analyzing the data. The tutorial then explains how to create a slicer table for filtering and implement an advanced search using DAX. It concludes with creating and evaluating filter expressions, encouraging viewers to practice with the provided resources.

What is the first step in performing an advanced search in Excel?

• Opening a new Excel file

• Applying a filter expression

• Creating a slicer table

• Loading data into a model

What is the purpose of the training table in the context of this tutorial?

• To apply filters to visuals

• To create a unique list of products

• To summarize the tools used in trainings

• To list all available Excel files

Why is it important to have a unique list of products when creating a slicer table?

• To visualize data in a report

• To connect tables using a measure

• To avoid duplicate entries in the slicer

• To ensure accurate data import

What function is used to iterate over the slicer table in the filter expression?

• SUM

• IF

• MAX

• SUMX

How does the search function contribute to the filter expression?

• It adds a starting position for the search

• It checks if a specific text is found within another text

• It calculates the sum of all values

• It creates a new slicer table

What should be done if the slicer table and training table are not connected?

• Use a measure to connect them

• Import data again

• Delete the slicer table

• Create a new slicer table

What is the role of the MAX function in the filter expression?

• To calculate the total number of trainings

• To ensure the same value is used for each row

• To create a new slicer table

• To find the highest value in the table

What is the result of applying the filter expression to the visual?

• It removes all data from the visual

• It displays all available tools

• It creates a new training table

• It shows only the trainings that include the selected tool

What happens when you select a tool in the slicer table?

• All tools are displayed

• Only trainings with the selected tool are shown

• A new training table is created

• The slicer table is deleted

What is the final step to ensure the filter works correctly in the visual?

• Import data again

• Create a new slicer table

• Apply the filter to the visual

• Delete the training table
