James Checks the Project Schedule and Investigates the Transfer of Dates
After Lisa, who works as a sales representative at Hybrid Machinery, has created the sales order, the project structure has been created automatically. It includes the network with all of its activities.
James, who works as a project planner at the same company, now checks the project schedule and investigates the transfer of dates from network activities to the network header and the WBS elements, to which the network activities are assigned.
A Work Breakdown Structure (WBS) with assigned networks and activities can be scheduled top-down or bottom-up. In top-down scheduling you first define the basic dates for the WBS elements manually. This might be the case if these dates are determined externally and are fixed for the project.
Usually in a logistics project bottom-up scheduling is used instead. Here, the network activities are scheduled first and the scheduled dates are transferred to the network header and the WBS element an activity is assigned to. Then the basic dates of the network header and WBS element can be derived automatically.
Networks are always scheduled forwards and backwards. The scheduling type in the scheduling parameters specifies the direction in which you begin the scheduling. The system determines the earliest dates of the activities by means of forward scheduling, and the latest dates by means of backward scheduling. The difference between the earliest and the latest dates of an activity are referred to as floats. Floats can be positive, zero, or negative. If the float of an activity is zero or negative, the activity in question is critical.
Relationships determine the chronological sequence of the individual activities in a network. You can enter additional data (such as a time interval or reference to a particular factory calendar) in the detail screen for each relationship.
The system is able to determine to sequence of network activities using relationships.
