In multiple selection, a process folder is split at a branch and forwarded via one or more outgoing flows. In the BPMN process diagram, there are two ways to do this:
Inclusive gateway
As soon as a process folder activates an inclusive gateway with multiple outgoing gates, one process folder with the same process number is forwarded to a subset of the subsequent objects (depending on the probability thereof).
Activity with multiple outgoing flows
As soon as an activity is completed, one process folder with the process number of the activating process folder is forwarded to a subset of the following objects.
The following applies for both possibilities:
Forwarding is based on probabilities by default. Probabilities can be defined for outgoing sequence flows (Simulation attribute type group, Probability attribute). The sum of the probabilities of all sequence flows should be greater than or equal to 1 and less than or equal to the number of gates. If this is not the case, or if no probabilities have been specified, the following rules apply:
If all probabilities have been specified and they are equal to 0, nothing is changed.
If some of the probabilities have not been specified, they will be set to 1.
