Hi, Iam using Drools 5.6 , developing rules on guvnor. I have a scenario where i have two decision tables , One is supposed to execute after the other. I want to ensure that DT Two should be executed only after all the executions in DT one happen . Because IN DT Two the list is being checked if set of values are not present, currently when i have two Customer objects in Working memory each having matching rows in Decision Table One .Once the match is found for a customer object then as per the action a Product fact is inserted which leads to fire the DT Two and the list is evaluated if set of d are not present , the rule is fired in DT Two as the list is not populated for the other customer object and matching rows which is being checked in DT Two eval list column. Which is not desired . I tried with salience , ruleflow group with not much of a help Is there a way to can handle this <http://drools.46999.n3.nabble.com/file/n4029371/DTIssue.png> *Decision Table One* Condition Condition Condition Action c:Customer a==$param b in ($param) c == $param "list(Global Variable).add(d); insert(Product())" *Decision Table Two* Condition Condition Condition Action p:Product a==$param eval(list doesnt not contain ($param)) c == $param response.setMessage($param); Regards Oggu -- View this message in context: http://drools.46999.n3.nabble.com/Rule-Orchestration-tp4029371.html Sent from the Drools: User forum mailing list archive at Nabble.com.
