A customer has several one-time payment plans within a tenant.

If you want to restrict employees so they can only submita single one-time payment per payment event, you must ensure thatMultiple One-Time Payments is not enabledin tenant setup.

When disabled, Workday enforcesone plan per effective date/reason.

Why not the others?

A. Segment security→ Controls data access, not number of payments allowed.

B. Rule-based BP→ Governs approvals/workflow, not structural system behavior.

C. Enable Multiple One-Time Payments→ Would allow multiple entries (opposite of requirement).
