The Event Sequence filter uses an event sequence editor to create its criteria. This allows you to specify event sequences in great detail. This editor can be opened by pressing the button to the far right of the filter.
This window can be used in Basic mode or Advanced mode. The mode can be switched at any time by pressing the Switch to Advanced/Basic link in the bottom left corner of the window.
In Basic mode, most of the window is taken up by a list of events. To add a new event, click Add. This will bring up an Event Criteria window filled with additional filters. Click any of the text fields to enter information. A drop-down menu will also open when you click on certain fields. These criteria filters will tell the Event Sequence filter which types of events to look for when it scans through calls. If the events appear in the correct order, regardless of any other events that may happen between them, the call will be allowed through the filter.
Advanced mode opens a new list in the bottom half of the window that contains exact order requirements for the sequence. Add new requirements by clicking the Add Row button to the right. After adding events to the event list above, you can select them in the left or right drop-down menus on each row below. Between the two boxes is a list of options for relationships between the two events. Follows is the default option for Basic mode, but here, you can choose from multiple types of Follows and Precedes, including Immediately Follows and Immediately Precedes. These will only accept calls where the two events are right next to each other. You can also choose Does Not Immediately Follow/Precede or Never Follows/Precedes to exclude calls where the two events appear next to each other or anywhere in the same call.
Press OK when you're finished creating criteria and requirements. The Add Report Column window will be updated with your new filter.
