Configuring KPI Calculation
KPIs and KPI elements are calculated for equipment during scheduled shifts. For KPI elements and KPIs to be calculated, perform the following configurations:
2. On each piece of equipment for which KPIs are to be calculated:
* 
As a best practice, configure KPI calculation before configuring the statuses for the equipment. KPI calculation for a piece of equipment begins once the equipment status is no longer Not Configured. If KPIs are calculated for a piece of equipment before the KPI elements are defined, the KPIs are calculated without meaningful data.
* 
By default, ThingWorx Apps supports calculating KPIs for up to 500 equipment Things. If this limit is exceeded, then the list of all equipment Things that are configured for KPI calculation is sorted alphabetically by name. The first 500 are then selected for KPI calculation.
This limit can be changed by overriding the GetKPIElementsFromTimeInfo service on the default KPI manager (PTC.SCA.SCO.DefaultKPIManager), and changing the MAX_ITEMS value. Increasing this value can have a negative impact on performance.
