Enabling a report as a worklet and assigning it to a dashboard does not automatically make it visible. The Recruiting dashboard (or any dashboard in Workday) must beconfigured to include the workletexplicitly. This is a common oversight—report designers assume that enabling a report as a worklet is sufficient, but the dashboard itself must be updated in configuration to display that worklet tile.

From the Workday reporting materials:“Dashboards provide an interface to view multiple worklets. Even if a report is enabled as a worklet, the dashboard configuration determines which worklets are visible to end users.”

Thus, the correct reason isB. You need to configure the Recruiting dashboard to include the worklet.
