Rule Builder > Managing Decision Trees > Checking Capabilities > Checking for Overlap

To check for overlap, do the following:

Figure 13.50 shows an example of the isBetween predicate. The check looks for interval overlaps in the defined decision nodes. An overlap has been found, the decision node and the overlapping test link intervals are highlighted in red, and an error icon images/dtree_warnicon.png is displayed.

Overlap is checked for any type that supports the isEqual and isIn predicates. In addition, isBetween is checked for Number and Date, but not String.

If you place the pointer over the images/dtree_warnicon.png icon next to the decision node, the tooltip explains the error, see Figure 13.51.
