PL-900 Demonstrate the capabilities of Power Apps Practice Question
A company uses Power Apps to build a leave request app. Managers must approve requests only if the employee has sufficient leave balance. Which approach ensures the balance is checked before submission?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the SubmitForm function with a validation formula checking leave balance
The SubmitForm function in Power Apps can include a validation formula in the Items property or via the OnSelect property to check the leave balance before the form is submitted, preventing submission if the balance is insufficient. Option A is wrong because Power BI is for analytics, not validation. Option C is wrong while it can auto-reject, it does not prevent submission, and the requirement is to check before submission. Option D is wrong because foreign key constraints in Dataverse cannot dynamically check leave balance based on current data.
