Question
A company creates a canvas app.
The app requires users to enter their social security number. The app should only display the last four digits when the user tabs to a different column.
You need to configure the app.
Which option should you use?
- A. Business rule
- B. Business process flow
- C. Power BI DAX
- D. Power Fx Correct
Explanation
Power Fx is the low-code formula language of canvas apps. Formulas on the input controls, for example using Right(TextInput.Text, 4) to show only the last four digits once the control loses focus, can mask the social security number after the user tabs away. Business rules and business process flows are Dataverse features for model-driven forms and processes, not canvas app control logic. DAX is the Power BI formula language and isn't used in canvas apps.
