Multiple commitments occur when several operations are scheduled to start or finish at the same time on a work center. This can happen for different reasons, depending on the settings of the strategy profile and the work center. Two possible reasons are:

The Finite Scheduling indicator is NOT set in the strategy profile. This means that the system does not consider the capacity availability of the work center when scheduling the operations. The system only checks the basic dates and the relationships between the operations. Therefore, the system can schedule multiple operations at the same time on the same work center, resulting in multiple commitments.

The work center has several individual capacities. This means that the work center can perform several operations simultaneously, depending on the number and type of individual capacities. The system assigns the operations to the individual capacities based on the capacity category and the priority. However, if the individual capacities have the same capacity category and priority, the system can assign multiple operations to the same individual capacity, resulting in multiple commitments.
