Instead of creating 3 Knowledge bases you can have one KnowledgeBase with all three decision tables and then each decision table will have a "Salience" to control the priority of execution. DT1 has highest Salience and DT3 has lowest value. When you upload these DT into Drools BRMS you will have one binary package for all these three DTs even though you define different packages for each one of those DTs. Is that the case ? ________________________________ From: HonorGod <jagadeesh.motamarri(a)barclayscapital.com&gt; To: rules-users(a)lists.jboss.org Sent: Fri, January 15, 2010 11:47:21 AM Subject: [rules-users] Is this possible in Guvnor? Hi, I have a single fact model with 5 [a1, a2,a3, a4, and a5] different attributes. I have 3 decision tables in the following fashion Decision Table 1 --------------------------------------------- condition | condition | condition | Action | --------------------------------------------- a1 | a2 | a3 | a4 = a1+a3| ---------------------------------------------- Once I have the value of a4, I need to hit different set of rules which are stored in second decision table Decision Table 2 --------------------------------------------- condition | condition | condition | Action | --------------------------------------------- a1 | a2 | a4 | a5 = a4 | ---------------------------------------------- Once I have the value of a5, I need to hit different set of rules which are store in third decision table Decision Table 3 ------------------------------------------------------------------------ condition | condition | condition | condition | condition | Action | ------------------------------------------------------------------------- a1 | a2 | a3 | a4 | a5 | computeValue() | ------------------------------------------------------------------------ I don't have any problem when I load the rules into individual KnowledgeBase and fire the rules one after the other as follows - <code> // apply rules from decision table 1 StatefulKnowledgeSession kSession = knowledgeBase1.newStatefulKnowledgeSession() ; kSession.insert(caEventDO); kSession.fireAllRules(); // apply rules from decision table 2 kSession = knowledgeBase2.newStatefulKnowledgeSession() ; kSession.insert(caEventDO); kSession.fireAllRules(); // apply rules from decision table 3 kSession = knowledgeBase3.newStatefulKnowledgeSession() ; kSession.insert(caEventDO); kSession.fireAllRules(); kSession.dispose() ; </code> But when I upload the decision tables into Guvnor and use the package / drl from the package snapshot my second set of rules are not fired at all. How do I resolve this issue? Please help.

I got the point....will you be able to attach that sample excel?

Also, I am still confused on how to use AGENDA-GROUP and RULEFLOW-GROUP in decision tables. I understand that XOR-Group / Activation-Group are used so that only one rule in this named group will be fired. Can you please explain ?

Thanks for your help.
