In Workday,custom validationsare evaluated based onbusiness process context, including theevent typethat triggered the process. The Request One-Time Payment and Request One-Time Payment for Self are separate event types, even though they share similar functionality.
To prevent existing validations from running for employee self-service requests, administrators mustexplicitly exclude the self-service event typewithin the validation logic. This is done using theMaintain Custom Validationstask, where conditions can be added to evaluate theOne-Time Payment Event for Selffield.
Security changes are not appropriate because the requirement is to allow the process but exclude validations.
Optional field configuration does not control validation execution. Creating additional validations does not stop existing ones from firing.
By excluding theOne-Time Payment Event for Selfevent type within the validation, Workday ensures validations continue to apply to administrator-initiated requests but not to employee self-service requests.
Therefore, optionCis the correct and Workday-supported solution.
