The Candidate Workload Report window is divided into two panels:
- The left panel displays the selected workloads in the Workloads tree. After a split or merge, the workloads tree is updated so that workloads appear according to their evaluation order. See Evaluation Order of Candidate Workloads for more information.
- The right panel displays the Workloads Report. This is a list of available workloads.
For more information on how to navigate the options in the Candidate Workload report, see Overview.
