Assign Employment Identifier for Worker (IRL)

Assign Employment Identifier for Worker (IRL)

Security:
Worker Data: Payroll (Company Specific) - IRL
 domain in the IRL Payroll functional area.
Workday typically generates the employment identifier automatically for:
  • New hires.
  • Rehires.
  • Transfers to a company with a different employer registration number (ERN) or from a company outside Ireland.
In some rare cases, Workday doesn't automatically assign the identifier, such as when you:
  • Add workers to an Irish payroll pay group using the
    Assign Pay Group
     web service.
  • Use the
    Assign Pay Group
     task and the effective date for the employment identifier is the same as the worker's hire, rehire, or transfer date, including when the worker transfers to a company with a different ERN.
  • Migrate employment identifiers from a legacy system and use the
    Assign Pay Group
     task to add workers to Irish payroll pay groups.
In these cases, or when the identifier has loaded incorrectly, you can add an employment identifier using the
Assign IRL Employment Identifier
 task, which enables you to:
  • Generate an employment identifier automatically for a worker.
  • Enter an existing employment identifier manually for the worker.
Don't add a new employment identifier for a worker when one already exists for the employment, as Revenue may record it as a separate employment.
  1. Access the
    Assign IRL Employment Identifier for Worker
     task.
  2. Complete the task:
    Option
    Description
    Generate Employment Identifier
    Select the check box to enable Workday to generate an employment identifier for the worker.
    Employment Identifier
    Enter a unique identifier that hasn't previously been assigned to the worker in Workday.
    Effective Date
    Enter the worker's:
    • Hire date when you hire a new worker.
    • Rehire date when you rehire a former worker.
    • Transfer date when you transfer a worker to:
      • An Irish payroll pay group from a company outside of Ireland.
      • Another Irish company with a different ERN.
    When you create an employment identifier using the
    Assign IRL Employment Identifier for Worker
     task, you can't edit the identifier's effective date.
    Don't assign a new employment identifier when you transfer a worker to another company under the same ERN.
The employment identifier displays on the:
  • Tax Details
     tab of the worker profile.
  • View IRL Employment Identifier for Worker
     report.
  • View IRL Worker Tax Details
     report.
You can edit the employment identifier before you calculate payroll results for the worker, but not afterwards. You can't delete employment identifiers, but you can correct and rescind them.
Workday automatically updates employment identifier information when you correct these details on a staffing business process event:
  • Company.
  • Effective date for hire or change of company.
  • ERN.
See Correct Staffing Events.
When you rescind these details on a business process event, Workday automatically deletes the associated employment identifier:
  • Company.
  • Organization.
  • Pay group assignment.
You can't correct or rescind staffing events once calculated payroll results exist for the worker.
Correcting or rescinding business process events that affect employment identifiers can inactivate identifiers. Examples: You rescind a hire event or a worker's transfer to another company under a different ERN. Access the
View IRL Inactive Employment Identifiers
 report to find workers with inactive identifiers.
When an employment identifier becomes inactive, you may need to update Revenue Online Services with the worker's end date in order to deregister the worker under the ERN.
