Documentation
Definition
Defines in SAP APO whether the system synchronizes the start times of activities on multi-mix resources and multi-activity resources when these activities have the same duration and a further identical characteristic.
Use
When synchronizing, the system schedules the new activity either at the same start time as an activity with the same duration and characteristic (which has already been scheduled) or, without overlap, before or afterwards. By synchronizing, you can create blocks of activities at the multi-resources that can be processed simultaneously because they have the same duration and characteristic. You specify the value of the characteristic by using a setup group or a setup key that you assign to the operation in the production process model.
If the desired start or finish time of an activity falls between the start and finish time of an activity that has already been scheduled with the same characteristic and duration (that is, an overlap has occurred) the system schedules the activity on the same start time as the activity already scheduled, if there is sufficient capacity. If there is not enough capacity at this time, the system schedules the activity before the scheduled activity (scheduling direction backwards) or after the scheduled activity (scheduling direction forwards) without overlap. The system always schedules activities with different durations and characteristics without overlaps.
If you select No synchronization, the system schedules activities on multi-resources with overlaps.
The system only executes synchronization for multi-resources that you only use as primary resources in the modes of production process models.
Example
Synchronization can be used to model the loading of an oven. Because the oven can only be loaded or unloaded all at once, you must ensure that it is filled to full capacity with products that require the same temperature and duration. Therefore you can only schedule activities for the oven that have the same durations and require the same temperature. Tempering activities with a different duration or temperature can only be loaded into the oven without overlap either before or afterwards. You can model different temperatures using different setup keys that you assign to the operations, and hence to the activities of the operation.
Notes
Note that the setup key and setup group are used differently for multi-resources than for single resources:
- For single resources, the setup key or setup group classifies the setup status of a primary resource that is required for processing an operation.
The setup status of a resource is evaluated by the system during the setup time adjustment or in setup time optimization based on the setup matrix.
- For multi-resources, the setup key or setup group represents a characteristic of an operation that you wish to use for the synchronization of activities on a primary resource (for example, a certain temperature).
