Decision Tables and Scripting Rules are strong tools for decision making, but they can be even stronger when working together.
As a DecisionRules user, you may already know that you can create rules in the form of Decision Tables or Scripting Rules. These two features can be also combined in Rule flow, which is used for more complex rules/conditions. However, it is also possible to call the Decision Table directly from the Scripting rule!
Decision Tables and Scripting Rules differ in the ease of creating the conditions inside DecisionRules. Decision Tables are designed as user-friendly as possible even for non-technical people. Even though we offer a large set of different operations and operators, sometimes it can happen that it is still not enough for certain more complex use-cases.
For a better picture, imagine the case when you are letting your employees / teams / customers register to your system. But for being registered, for example for certain benefits, the user needs to accomplish some conditions. Sure, the majority of those conditions could be easily specified in Decision Tables. But sometimes there are conditions that must be evaluated within a group of users. And exactly at this moment, embedded rules in Scripting Rules are coming to the scene.
This feature can be used very easily. All you need is to know the ruleID and employ the right method. The method is called solve().
As you can see, the rule is called via DR.solve(ruleId, data, version, SolverStrategy). For more details, see the tutorial in our documentation.
From the previous formula it is now visible that there are other parameters that have to be specified before running the solver. The first parameter, as was mentioned before, is the ruleId. Then obviously you need to have input data for your solver, and then specify the version of the rule you are going to use. The last parameter is the execution strategy (Standard, First match, ...) and you are good to go!

Commissions play a pivotal role in various industries, especially in the financial sector. In this article, we dive into the practical implementation of commission management and calculation using DecisionRules.io. In the first part, we'll explore the layers of the commission calculation model, rule variables, activation management, and input/output models. In the second one, we will look into examples of concrete rules, integration of DecisionRules with external systems, and Reporting of Commissions.
