Object-centric and case-centric filters
When configuring filters in the Celonis Platform, the feature name displayed depends on whether you're using an object-centric or case-centric data model.
Object-centric data model: Event filter
Case-centric data model: Activity filter
Event (object-centric) and activity (case-centric) filters allow you to refine and analyze your process data by focusing on specific activities within the process. Using an event / activity filter allows you to filter out unnecessary or irrelevant events, enabling a more targeted analysis of workflows, bottlenecks, inefficiencies, or deviations in that process.
In this example, an activity filter is being applied to a Process Cockpit View (using a Process Explorer component). The activity filter is configured to only show objects where the 'Approval' activity is excluded, filtering down the objects displayed to 26% of the data model. This filtered data set can then be used to examine why approvals are being skipped in a process.

Using an event / activity filter can be beneficial in a number of ways, including:
Enhanced data clarity: Reduces unnecessary complexity in large datasets, making insights more actionable.
Improved process efficiency: By focusing only on relevant events, you can quickly identify process inefficiencies and find root causes of issues.
Better compliance and risk management: Identifies process deviations that could lead to financial or legal issues, such as broken SLAs or delivery deadlines.
Customizable per use-case: Your filters can be set for different process stages (e.g., time from order placement to shipment). You can also analyze short, medium, and long term cases separately.
When process filters are enabled, users can apply event filters by clicking Filters - Event / Activity filter:

You can then configure the following:
Event log: Event logs describe the sequence of activities happening for your cases e.g. all activities related to your purchase orders.
Start / End / Include / Exclude: Choose how the filter will interact with the activity or activities that you're selecting.
Activity / activities: Select one or more activities to filter your data by.
