A customer has several one-time payment plans in their tenant.

By default, Workday allows only one one-time payment per event when the Enable Multiple One-Time Payments tenant setting is not enabled. This behavior ensures strict control over one-time payment submissions and prevents multiple payments from being entered within the same transaction.

The Enable Multiple One-Time Payments setting in Edit Tenant Setup – HCM > Compensation explicitly removes this restriction and allows users to submit multiple one-time payments with the same reason and effective date. Since the business requirement is to limit submissions to a single payment, this setting must remain disabled.

Security configuration and business process rules do not control the number of one-time payment rows allowed in an event. They only manage access and approval flow.

Therefore, to enforce a single one-time payment per event, administrators must not enable the Multiple One-Time Payments setting, making option B correct.
