Just point your browser to the appRules URL {% endhint %} {% hint style="info" %} The completed project is available in the appRules **Samples** project database. Click the "Open" toolbar button on the appRules home page to select the "Decision Table - Customer Discount" project. {% endhint %} EvaluateDecisionTable is the only workflow activity required for configuring a decision table in appRules. It can be accessed from the **Business Rules** module in the toolbox. For simplicity, we have used a single activity in this sample project. In an actual project, the EvaluateDecisionTable activity is used in conjunction with other activities. Also, in this sample, the values to be evaluated are passed to the EvaluateDecisionTable activity from the arguments used to run the project. In an actual project, the values passed to the activity typically come from record values in data sources such as CRM, ERP, Databases, etc. The project can also be called via the appRules WebAPI. {% hint style="info" %} Note that the **View Execution Results** box of the EvaluateDecisionTable activity is checked to display the result when the activity is executed. This is the practice for debugging appRules activities. At deployment, the View Execution Results box is automatically deactivated if the project is not run in interactive mode. {% endhint %} You can experiment with this project by making changes and running the project to view results. No external data sources are required.
