Sometimes when debugging, an inferred attribute may have a different value from what you expected based on the input data. In this case you will want to see the decision that led to the value. To understand a decision:
Select the attribute in the Data view, right-click and select Show Decision. (If there are multiple values for the attribute, you also have the option to show the decision for a particular value from that change point.)
The decision report for this attribute is shown in the Decision view, in which you can also show the relevant rule. (If you have opted to show the decision for a particular value, the Decision view will limit the relevance period for the decision tree to the period from the current change point to the next change point for the attribute. In other words, only attributes relevant to proving the value of your chosen goal within the relevance period, will be displayed in the Decision Report. Note, however, that any attribute which is displayed in the Decision Report, will display its whole timeline in {curly brackets} after the attribute text, and not just the portion of the timeline which is relevant to proving the value of your chosen goal within the relevance period.)
When you review the reasons for a decision, you might uncover a logic error in your rules. To update your rule:
Firstly, save your debugger session so that you will be able to retest any changes that you make to the rulebase. (For more information, see Change a rule while debugging.)
