Processes models shall enable a better understanding and management of business processes as well as the information systems implementing these processes.
Usually, different stakeholders of various enterprise levels are interested in process models which raises specific requirements concerning process model abstraction.
While business managers are interested in high-level (i.e., abstract) process views, process participants need more fine-grained process views during process enactment.
This also applies to many legacy software systems that implement business processes, but were originally not designed to provide process model details.
In this paper, we present an approach for preprocessing event logs obtained from legacy software systems such that process models of different granularity levels can be discovered from them.
