Symptom
In an Investigation of a Process, adding a filter with an Event Log attribute, it doesn't work as expected.
Environment
SAP Signavio Process Intelligence
Cause
This is a known limitation that the filters only works on Case level.
Resolution
This is basic principle of the current filtering mechanism.
If you filter with an "Event Log Attribute" it will filter for cases where at least one event has a matching value.
If you want to filter on event-level then you'd have to write the SIGNAL code for that.
