ELSE-Rule

The ELSE-rule is the rule that applies when all of the "actual" rules of the decision table were not satisfied. As such, a condition cannot be entered in the decision table editor there.

The ELSE-rule typically handles either errors (output of a message, possibly followed by a stop (f$Stop) or "normal" cases (when the rules handle the special cases).

Before saving a decision table, it is always a good idea to consider what the ELSE case for the current DT means, and possibly incorporate an error message or stop.
