Executing a Decision Model and Notation (DMN ) is essential; otherwise, it cannot automate decisions or ensure consistent outcomes. Creating business rules and decisions in DMN requires Decision Requirement Diagrams (DRD), Boxed expression, Friendly Enough Expression Language (FEEL), and Decision tables; all of these components are executable visually.
To execute The DMN model, we need inputs. Users can click on the Play button or use shift+F5 or from the top toolbar Debug --> Run to add inputs to the model and execute it.
Start to execution of the Decision model and notation (DMN) model by applying input
Click on the Run icon to run a model in execution mode. The first step asks for input value.
A logic run template, which includes your created Run Template, can also do this.
After clicking on the Play button, your model starts to execute. You can see the result and many details from the execution in the parameters window.
Executing all the elements in the DMN model
To execute and explain this capability, we select the DRD for the routing decision example.
After writing or selecting the input value and executing the model, the Parameters window displays all the inputs, local, and output parameters.
FlexRule allows users to show all the details of the execution. By clicking on the Event Viewer, users can see many details about the execution, such as the time consumed for each logic document or which rule is executed in any logic document. You can see all the details of the Event Viewer on this Resource Hub page.
Summary
Executing the Decision model and notation (DMN) model means the decision and rules are converted into a format that allows them to be applied automatically to real-world data. In the Executing mode, you can run any DMN model in FlexRule Designer. That means you can get more details information regarding logic execution. This happens when you click on the Run Icon and provide input.
