DMN Decisions

The application provides comprehensive support for DMN (Decision Model and Notation) decision tables through the DMN → Decisions menu item.

Selecting this menu item displays a comprehensive list of all decision tables currently deployed to your active BPM engine.

Decision definitions and instances are displayed using historical data.

Decision Table List

The Decisions view displays all DMN decision tables deployed to your active BPM engine in a sortable, filterable table format.
