A routing can be scheduled using the following scheduling types:
Forward scheduling: The system schedules forward starting from the basic start date.
Backward scheduling: The system schedules backward starting from the basic finish date.
"today" scheduling: The system carries out forward scheduling using the current date as a basic start date.
no scheduling: The individual operations are not scheduled.
Based on the floats before and after production, the system calculates the scheduled start and finish and enters these dates in all operations.
The scheduling type determines which basic dates you have to enter. The following table shows the dates you must enter for the individual scheduling types as well as the dates that are then calculated using scheduling.
If you enter both basic dates, the system will make sure that the dates determined using forward or backward scheduling are within the specified period. If necessary, it will apply reduction measures.
Example Data
Material shortage date
01.08 (Friday)
Planned delivery time of the material
10 days (calendar days)
Processing time for purchasing
1 day (workdays)
Goods receipt processing time
2 days (workdays)
Opening period
10 days (workdays)
Workdays = Monday to Friday, no bank holiday
Scheduling
Material shortage date plus processing time for purchasing plan plus planned delivery time = delivery date
01.08. (Friday) plus 1 workday + 10 calendar days = 14.08. (Thursday)
Delivery date plus goods receipt processing time = availability date
14.08. (Thursday) plus 2 workdays = 18.08. (Monday)
