Input Data

An InputData Element is used to input into Decisions a set of values that originate outside the model. That set of values are used for evaluating Decisions. It derives it's type and a set of values from an ItemDefinition.

Overview

InputData elements are created by dragging an InputData-type icon from the Toolbox onto a DMN diagram. 

The name of the InputData element must be unique and not duplicate the name of any other decision, input data, business knowledge model, decision service, or import in the decision model.

Referencing an ItemDefinition

The structure of the data, as well as sets of values for an InputData element are defined in an ItemDefinition Element.  A DMN InputData Element must be referenced (typed) by an ItemDefintion using either:

  • The icon on the DMN Expression window of the InputData Element or
  • Selecting the InputData Element and pressing Ctrl+L to select the ItemDefinition from the dialog.

Input Data properties

The properties of an InputData element are accessible via the DMN Expression window. Double-click on the InputData element to open this window.

The DMN Expression window provides a view of the data structure as well as access to Data Sets that can be used in simulations.
