Multiple Assigner Activity obtains partitioning instance from exactly one Single Instance Flow
Single Instance Flow delivers partitioning instance to zero or one Multiple Assigner Activity
Each Multiple Assigner Activity has access to a flow providing a reference to the parititioning instance (the instance establishing scope of competition managment for the assigner during runtime). This is exactly one instance, so it is delivered via a Single Instance Flow.
Any given Single Instance Flow may or may not be the one delivering the partitioning instance reference.
