Decision tree editing errors and warnings

Rule Designer checks for overlaps and gaps in decision tree conditions, and indicates problems by using visual cues.

If there is an error or warning in a decision tree, the warning symbol Error identifies the affected nodes and branches.

When you save the decision tree, the Problems view also displays the errors and warnings.

A decision tree that has a checking error cannot be run, unless you disable checking.

The rules that make up your decision tree can be checked for gaps and overlap. You can specify your checking preferences at node level and at tree level.

Gaps

Rule Designer checks that the branches in the decision tree are uninterrupted. For example, if one branch defines the interval [21 - 30] and another branch defines the interval [33 - 40], an error is generated because the interval [31 - 32] is not accounted for.

Overlap

Rule Designer checks that no branches overlap in the decision tree. For example, if one branch defines the interval [21 - 30] and another branch defines the interval [28 - 40], an error is generated because the interval [28 - 30] overlaps in that node.

Note:

You cannot check dates for gaps and overlap.
