The Decision Table menu allows you to access the decision matrix. This Decision Table gives you the possibility to create a custom decision table by adding inputs and outputs in form of text, numbers, Boolean (true or false) statements, collections and more. You can also define rules for each set to find the best desired outcome.
The Decision Table in the context menu performs the same actions as the DMN ribbon. Please consult the Decision Table function in the DMN ribbon tab for more information.
