Drillthrough
Summary view has a drillthrough feature that allows you to quickly see processes where specific event occurs.
Understand drillthrough
Let's consider these 3 simple processes as example:
Here's the same data in Summary view. When node is hovered in Summary view a "Related processes"-button appears above.
From that button you can drillthrough back to Process view, but now only processes that contain Event C are included.
In this example they are processes 1 and 2. Process 3 does not contain Event C.
