[rules-users] decision tables and default rules for case when part of LHS failes for other rules

Hi all, I have been asked to add default rules to a decision table. We have a decision table with several conditions. Data from first two columns are passed to action with binded variables. The action collects data from all passed rules. ------------------------------------- condition 1 | condition 2 | ... | action ------------------------------------- AAA | AD | ... | X ------------------------------------- BBB | AD | ... | X ------------------------------------- BBB | AE | ... | X ------------------------------------- BBB | CC | ... | X ------------------------------------- CCC | AD | ... | X ------------------------------------- DDD | AD | ... | X ------------------------------------- BBB | AE | ... | X ------------------------------------- ... | ... | ... | X ------------------------------------- Recently business asked me if it is possible to have default rules (rows) in the table if there is not any rule passing condition 1. ------------------------------------- DEFAULT | AD | ... | X ------------------------------------- DEFAULT | AE | ... | X ------------------------------------- Is it possible to have rules in decision table those can be fired only if a specific part of LHS never occurs in others rules?
