To set up What-if Modeling, you need to do the following:
In the Person Change window, add the What-if label to person data changes. You must do this for data changes to display in Self-Service Benefits What-if.
Attach the Benefit Compensation Objects EIT to the Responsibility. Your EIT setup determines the compensation objects you want to include or exclude from the compensation object hierarchy.
See: Setting Up Extra Information Types Against a Responsibility
Define Roles from the Maintain Roles window. This is optional, and you can configure this if you want to restrict which plans display based on the role of the self-service user.
Save your work.
