Disabling Utilization Calculation

The Disabling Utilization Calculation custom setting allows you to enable or disable utilization calculation. This setting is enabled by default. Use this setting to disable utilization calculation and use utilization analytics to manage Utilization.

To disable the legacy utilization calculation feature:

Remove the PSA - Calculate Utilization permission. For more information, see Assigning and Removing Permission Sets. This removes the legacy Utilization tabs. Skip this step if you do not have PSA - Calculate Utilization permission.
Navigate to Setup | Custom Settings | Utilization, click the Manage link next to Utilization and then click Edit.
Deselect the Use Utilization Calculation checkbox. The legacy utilization calculation feature is disabled.
