This activity is used to define selection criteria for system-defined selections. Selections are set when the automated KPI is based on user-defined value fields rather than fields that exactly match the KPI definitions. This is useful when the KPI depends on how specific fields are defined within the application. For example, when a KPI involves the total number of employees, it could include both employees and non-employees. Selections provide the flexibility to set criteria and values to accurately reflect the intended data.
