The HR administrator is complaining about a report that is running slowly.

Performance issues often occur when trending reports pull fields from related business objects instead of directly from theTrended Workers data source. This requires Workday to join across objects at runtime, slowing down report execution. To improve performance, you shouldadd the required field to the Trended Workers data source, ensuring the data is pre-joined and optimized for trending.

From the Workday binder:“To improve performance, add commonly reported fields directly to the Trended Workers object. Using related business object fields requires additional joins and increases report runtime.”

Creating calculated fields adds complexity rather than improving speed. Purging or re-creating trending data maintains system hygiene but does not address field-level performance.

Thus, the correct solution isA. Add the field to the Trended Workers data source.
