Defining the Calculation Schema for Downtime Default Values 

Use

The default values for downtimes are calculated by the system. The system usually calculated the times of the downtime elements that are assigned to the capacity category relevant for scheduling. If you want to include durations of downtimes from other capacity categories in the calculation, you must maintain the downtime schema accordingly.

Prerequisites

You are on the Enter Downtimes screen and have selected a resource there.

Procedure

  1. Choose Extras ® Downtime schema.

    2. The Calculation Schema for Downtimes screen appears.
