Chaining rules, including those in decision tables, can be achieved by using a transient control fact. rule "your DRL rule 1" when YourObject( field == 1 ) then insertLogical( new TransientControlFact( "dtable1" ); end rule "your DRL rule 2" when YourObject( field == 2 ) then insertLogical( new TransientControlFact( "dtable2" ); end Then in the decision table use the transient control fact in an additional column. The DRL would look like this:- rule "dtable1 row 1" when TransientControlFact( dtable = "dtable1" ) YourOtherFacts( ) then .... end rule "dtable1 row 2" when TransientControlFact( dtable = "dtable2" ) YourOtherFacts( ) then .... end How you retrieve the results from the Decision Tables is up to you (e.g. queries, globals etc).
