Network Scheduling (SAP Library

Network Scheduling

Use

Scheduling determines the earliest and latest start and finish dates for carrying out activities in the network and calculates the required capacity requirements as well as the slack time or "floats".

Features

What is Scheduled?

The following are scheduled:

Activities

Relationships

When is Scheduling Carried Out?

A network is scheduled:

If you create a network.

If you call up the schedule function.

When you save the network, depending on whether you have set the Schedule automat. indicator in the network header.

If you release the network, the indicator is set automatically and the network is scheduled each time you save it.

If you have made a change relevant to scheduling - for example, changed a duration in the activity or a relationship - and then have saved the network. This function depends on the settings you made in the scheduling parameters (Schedule automat. indicator).

If you make changes in the network which are relevant to scheduling, the system automatically sets the status "Dates are not updated" (NTUP).

Which Set of Dates is Used in Scheduling?

In the network, you can enter basic and forecast data for dates, duration, units, constraints and work. For scheduling, you specify in the network header, with which set of dates scheduling is to be carried out. In network maintenance choose Edit ® Settings ® Set of dates and then either Basic or Forecast. In the project planning board choose Settings ® Options, in the dialog screen the Planning board node and on the Settings tab page the relevant set of dates.

If you create a new network, the default is always the basic dates.

If you are working with an existing network, the set of dates with which it was last scheduled is always displayed.

For more information on the various dates in the Project System, refer to Types of Dates.

Scheduling Results

The system determines the following dates:

The scheduled start and scheduled finish of the network.

The earliest start and earliest finish (earliest dates) and the latest start and latest finish (latest dates) of the activities.

The earliest and latest dates of the relationships.

The reduction level used to reduce the duration in the network.

The slack time called "floats" (total float and free float) of the activities.

The capacity requirements for the activities.
