PAFnow Event Filter¶

With the PAFnow Event Filter you can discover deviations or compliance problems in your process. You can analyze the order of process steps in your process sequence and draw conclusions on the compliance with given rules. For the older versions below 2020.7 go here.

This is the icon of the Event Filter in the Visualizations pane:

How to get started¶

Before you can analyze the order of your process sequence with the PAFnow Event Filter, you have to drag the required fields into the respective buckets.

How to use¶

Once you have selected the necessary fields for the PAFnow Event Filter, you can start to analyze the order of selected process sequences.

Activities List¶

From this list you can drag the activities with which you want to create process sequences, and drop them into the graph in the corresponding drop-areas.

You can drag and drop as much activities as you want.

Build the Process Graph¶

Before you can start filtering and analyzing your process data, you first have to set up the process sequences to specify the process steps that you want to analyze.

To create the process sequences you have to drag the activities from the activities list and drop them into the graph in the desired position. You can drag the activity to the left, right, top or to the bottom of another activity in the graph.

Set Activities Relations¶

Once you've created your process graph you can now specify the relations between the activities.

There are four possible relations:

An activity can be Directly followed, Eventually followed, Not directly followed or Not eventually followed by the succeeding activity in the sequence.

Relation	Representation	Description
Include directly followed		Show all the cases in which the target activity of the edge took place directly after the source activity
Include eventually followed		Show all the cases in which the target activity of the edge took place any time after the source activity
Exclude directly followed		Show all the cases in which the target activity of the edge never took place directly after the source activity
Exclude eventually followed		Show all the cases in which the target activity of the edge never took place any time after the source activity

Set Gateways Type¶

The are two types of gateways:

• The exclusive gateway (default type): splits the sequence into two or more paths to create alternative paths that can be followed.

• The parallel gateway : splits the sequence into two to more paths that must be executed before reaching the closing parallel gateway. Here the order of the tasks execution between the opening and closing gateways is not important.

By clicking on the gateway, you can switch between the two types.

Choosing and Deleting Filters¶

In order to apply the selected filter, there must be at least one case in your data, that matches with the filter. You can see that on the end node of the graph. If it's a green apply-button then you can apply the filter. A yellow alert-button means that there are no cases that match the selected filter. Click on to apply the Event Filter. If all the cases match the selected filter, you will see a tooltip when hovering over the apply button. Click on to clear the set filter and the graph.

Once you've set the filter, a filter icon will be displayed on the top-left of the screen. To remove the filter, hover over the filter-icon and click the trash-can-symbol.
