The duration of operations is defined by the duration of the individual phases. The scheduling function calculates the duration of each phase.

Each phase is scheduled using the scheduling formula stored in the resource data. A phase network is scheduled and the phase order dates are carried over to the operation. The start time of the first phase plus the finish time of the last phase is the start and finish of the operation.

If you have entered the default values of phases in the master recipe, the system uses this data to schedule (using the order dates in the initial screen).

If one phase of an operation is relevant for scheduling, the whole operation must be relevant for scheduling.

If the operation is relevant for scheduling, then at least one phase must also be relevant for scheduling.

If the scheduling indicator is flagged in the control key, the operation or phase is relevant for scheduling.

The duration of the superior operation is defined by the duration of the individual phases.

You create temporal relationships between phases by maintaining their relationships. You can also maintain relationships between phases of different process orders.
