Unlike a realtime decision, within which the workspace is used to list decision criteria, a decision scorecard’s canvas is used to list weighted realtime decisions.
When displayed initially, a scorecard’s canvas displays a message:
You can use the Add New Weighted Realtime Decision button to add the same to a decision scorecard’s canvas. You can also add a weighted realtime decision by dragging a realtime decision from the toolbox and dropping it onto the canvas.
A weighted realtime decision has the following properties:
•Realtime Decision: provision of a realtime decision is mandatory. You can populate the property using drag and drop, or by browsing. When a realtime decision has been selected, you can open its latest version in the Rule Designer. You can also Clear the selected realtime decision. A realtime decision must have been saved to the RPI file system to be used in a scorecard.
•When: this dropdown field exposes values ‘Criteria met’ (the default) and ‘Criteria not met’. It specifies whether to assign a score should the selected realtime decision’s criteria be met or not met, as required.
•Apply Weight: a mandatory decimal value.
•Actions: this menu gives access to a single Remove option, invocation of which removes the weighted realtime decision without display of an ‘Are You Sure?’ dialog.
A validation error is raised when a weighted realtime decision is configured with a realtime decision that uses the current scorecard (thereby creating a circular reference), or when the same realtime decision is included more than once in a weighted realtime decision list.
Note that it is mandatory for a scorecard to contain at least one weighted realtime decision.
