Scheduling Computation Times
To chart a computation over time, you can configure computed fields to create deltas daily, weekly, or monthly. For a static computed field, this configuration also saves the values to the computed field’s column in the item row of the database. By default, the Windchill RV&S administration client includes scheduled event triggers that perform daily, weekly, and monthly computations. You can edit the triggers to create your own schedule for when computations occur.

When you run a scheduled computation trigger, computed fields are calculated in field order. If an item contains a computed field that depends on the value of another computed field, the computed field containing the dependent value must come first in the field order. For example, if Field B depends on the value in Field A, then Field A must come before Field B in the field order.
