When you create event logs in the object-centric perspective editor, you can now break down event types into subsets using their attributes, meaning that you can give your analysis an extra level of granularity without creating multiple similar events. For example, you can select the delivery method attribute to create subtypes of the ReleaseDelivery event, so that you can analyze each specific delivery method separately. If you later add a new delivery method as an attribute value, you won't need to set up a new event for it - it'll just appear as a distinct path.

You can select any number of attributes for any number of events in the event log, so you can create subsets of events based on combinations of attributes. We'll query the attributes in the order you place the events in the event log, followed by the order you place the attributes in the event type definition. If you need to change the ordering for different use cases, you can do that in the PQL query in Knowledge Models that use the event log.

You can break down an existing custom event log by attributes, and still continue to use the event log as you do now. We'll create a new activity column for events and attributes ending in _ActivityDetails, and keep the existing column ending in _Activity alongside it for events only.

With the new capability to add custom attributes to event types from the Celonis catalog (see Extend Celonis event types with attributes and relationships), you can use this feature with Celonis event types as well. Add the custom attributes to the Celonis event types, and create or edit custom event logs using them. Applications that don't know about the custom attributes will ignore them, so they won't affect your existing setup. For the instructions to model events, see Modeling objects and events.
