You created a new one-time payment plan and enabled employees to request payments for themselves.

Maintain Custom Validationsallows you to refine which events validations apply to.

Workday distinguishes betweenRequest One-Time Payment(manager/HR initiated) andRequest One-Time Payment for Self(employee initiated).

By using theOne Time Payment Event for Self field, you can exclude self-service events from being validated by the existing custom validations.

Why not the others?

B. Add new validations→ Would duplicate rules rather than exclude them.

C. Remove Employee as Self from security domain→ Would block employees from submitting requests, not exclude validations.

D. Configure Options Fields→ Controls fields displayed, not validation logic.
