Filtering the Process Map

Overview 

Filters may be applied to a Process Map to exclude certain activities, events, or executions from the analysis.

To create a Filter, select the Filter icon above the primary and secondary drop-down menus on the right and then select Add Filter. 

The Filter Log Selector can also be accessed in the Log Animation settings when animating multiple variants to apply filters to specific variants.

After creating a Filter, Users may toggle their appearance or delete them when hovering over a Filter in the Filter Log Selector.

Editing the Filter Log

The icons at the bottom of the Filter Log Selector allow Users to edit any created filters.

From left to right:

Filters Available

The following filter typologies are available:

Attribute Filter

Generally used to select executions containing common properties, the Attribute Filter is the most commonly used.

Users may configure this Filter further by retaining/removing executions or events possessing certain attribute values.

Acceptable values are defined by changing the specific attributes and phrases from the logic statement above the Filter view.

Duration Filter

The Duration Filter allows Users to retain or remove cases with durations or total waiting times, i.e., the sum of the durations of the handovers occurring in execution within a certain range. It also allows defining filters based on the duration of activities or handovers.

Endpoints Filter

The Endpoints Filter allows Users to retain or remove cases in which the start and end events have certain attribute values.

The Filter searches for the start event in the left column and the right column for the end event.

Frequency Filter

The Frequency Filter allows Users to retain or remove cases in which a certain number of activities are performed. The required number of activity executions is specified as a range. It is also possible to define filters based on the number of occurrences of a specific activity or handover.

Order Filter

The Order Filter allows Users to remove or retain cases in which there exists two events with certain property that are in a specific order relationship. There are four possible relationships: directly follow, never directly follow, eventually follow, and never eventually follow.

• Directly Follow: Of attributes A and B, B directly follows A in execution if at least one event with attribute value A is immediately followed by an event with attribute value B
• Never Directly Follow: B directly follows A in execution if there exists no event where attribute value A is immediately followed by an event with attribute value B
• Eventually Follow: B eventually follows A in a given execution if there exists at least one event with attribute value A that is followed by an event with attribute value B after an unspecified number of events.
• Never Eventually Follow: B never eventually follows A in execution if there exists no event with attribute A followed by an event with attribute value B after an unspecified number of events.

The two checkbox filter statements for orders with the following statements:

• The first statement checks other attributes for similar or different values for ordering.
• The second statement checks if the pair of events occurred within, started by, or ended by a certain time-frame for ordering.

Resource Filter

The Resource Filter allows Users to remove or retain cases in which certain activities are performed by certain resources.

Time-frame Filter

The Time-frame Filter allows Users to remove or retain cases occurring within a specific time-frame.

The Time-frame Filter supports four potential ranges:

• Started and Completed Within: Considers only executions with the first activity performed after the start date and the last activity performed before the completion date
• Started within: Considers executions with their first activity performed after the start date
• Completed within: Considers executions with their last activity performed before the completion date
• Active within: Considers executions with at least one event performed after the start date but before the completion date

Trim Filter

The Trim Filter will retain or remove events based on activities selected in the provided columns. The activity selected in the first column will be the start point, and the activity selected in the second column will be the endpoint. 

To Use the Trim Filter:

1. Select retain only or remove from the first Dropdown menu. This determines if the Filter will retain or remove activity executions.  
2. Select starting from or performed after from the second Dropdown menu. This determines if the Filter will retain or remove activity executions starting from or performed after the first or last activity execution.    
3. Select first or last from the third Dropdown menu. This determines if the Filter will retain or remove activity executions starting from or performed after the first or last activity execution for a selected attribute. 
4. Select an attribute from the fourth Dropdown menu. Once the attribute is selected, it will populate values in the left and right columns. Users can select values in either column to determine the activity execution values the Filter will retain or remove. 
5. The search box can be used to search through populated attribute values. Although values can be selected in either column, please note that the Dropdown menus must be used to specify parameters. 
6. Select ending with or performed before from the fifth Dropdown Menu. This determines if the Filter will retain or remove activity executions ending with or performed before the first or last activity execution. 
7. Select first or last from the final Dropdown menu. This determines if the Filter will retain or remove activity executions ending with or performed before the first or last activity execution.

• Click Apply. 
  • Make sure to select the chosen attribute from the Process View.  
  • The results should retain or remove activity executions within the specified parameters. 

Variant Filter

The Variant Filter allows Users to remove or retain cases that follow a specific execution variant.

When hovering over a variant in the chart, the Variant Filter shows the number of executions it appears within.
