Filtering the Process Map

Overview 

Filters may be applied to a process map to exclude certain activities, events, or executions from analysis. To create a filter, select the filter icon located 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 onto specific variants. After creating a filter, users may toggle their appear 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. Users may also rename filters once they have been created.

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 filter. 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 an execution within a certain range. Additionally, it also allows to define filters based on the duration of activities or handovers.

Endpoints Filter

The Endpoints Filter allows users to retains 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 searches the right column for the end event.

Frequency Filter

The Frequency Filter allows users to retains or remove cases in which a certain number of activities are performed. The required number of activity executions is specified in the form of a range. Additionally, 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 an execution if at least one event with attribute value A which is immediately followed by an event with attribute value B.
  • Never Directly Follow: B directly follows A in an 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 an execution if there exists no event with attribute A that is followed by an event with attribute value B after an unspecified number of events.
• There are four possible time frame relationships that the Order Filter can maintain: Started Within, Completed Within, Started and Completed Within, and Active Within.
• The two checkbox filter statements further 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 timeframe for ordering.

Resource Filter

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

Timeframe Filter

The Timeframe Filter allows users to remove or retain cases occurring within a specific timeframe. The Timeframe Filter supports four potential ranges:

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

Variant Filter

The Variant Filter allows users to remove or retain cases which follow a specific execution variant. When hovering over a variant in the chart, the Variant Filter shows the number of executions it appears within.
