What Epic feature enforces that required fields must be filled before saving?

• A. Mandatory Fields Validation
• B. Data Validation
• C. Field Enforcement
• D. Required Field Gate

Answer: (A)

Enforcing that required fields must be completed before saving is handled by mandatory fields validation. This mechanism marks certain fields as required in the form or data model; when a user tries to save with any of these fields left empty, Epic blocks the save and prompts the user to fill in the missing information. This behavior keeps data complete and consistent across records, which is essential for accurate documentation, reporting, and downstream workflows. Data validation is a broader idea that can apply to various checks, but the phrase that exactly captures blocking a save until all required fields are filled is mandatory fields validation. The other terms aren’t standard Epic labels for this specific enforcement.
