Hi, I have the following rules that I am trying to implement in a decision table rule "Payment greater 5m" agenda-group "txnPricing" salience 5 when payment : Collection() from bc.getPaymentTransactionTypes() t : Transaction(customer == c, transactionType memberOf payment, transactionAmount >= 5000000) then t.setBaseFee(36.00); t.setFeeDiscount(0.00); end rule "Payment less 5m" agenda-group "txnPricing" salience 5 when payment : Collection() from bc.getPaymentTransactionTypes() t : Transaction(customer == c, transactionType memberOf payment, transactionAmount < 5000000) then t.setBaseFee(60.00); t.setFeeDiscount(0.00); end I have attached the Decision Table for reference. Basically, I have two condition columns representing the 2 conditions respectively. When the xls is processed the generated DSL has the two statements reversed as indicated below, and hence the exceptions. package za.co.fnb.billing; #generated from Decision Table import java.util.Collection; import za.co.fnb.billing.Customer; import za.co.fnb.billing.Transaction; import za.co.fnb.billing.BillingConstraints; global Customer c; global BillingConstraints bc; #From row number: 12 rule "Payments_12" when t: Transaction(customer == c, t.transactionAmount >= 0, t.transactionAmount <5000000, transactionType memberOf $payments) $payment : Collection() from bc.getTransactionTypesForGroup("Payments") then t.setBaseFee(60.00); t.setFeeDiscount(0.00); end #From row number: 13 rule "Payments_13" when t: Transaction(customer == c, t.transactionAmount >= 5000000, t.transactionAmount <9999999999, transactionType memberOf $payments) $payment : Collection() from bc.getTransactionTypesForGroup("Payments") then t.setBaseFee(36.00); t.setFeeDiscount(0.00); end org.drools.rule.InvalidRulePackage: Unable to return Declaration for identifier '$payments' : [Rule name=Payments_12, agendaGroup=MAIN, salience=0, no-loop=false] Unable to create restriction '[VariableRestriction: memberOf $payments ]' for field 'transactionType' in the rule 'Payments_12' : [Rule name=Payments_12, agendaGroup=MAIN, salience=0, no-loop=false] Unable to return Declaration for identifier '$payments' : [Rule name=Payments_13, agendaGroup=MAIN, salience=0, no-loop=false] Unable to create restriction '[VariableRestriction: memberOf $payments ]' for field 'transactionType' in the rule 'Payments_13' : [Rule name=Payments_13, agendaGroup=MAIN, salience=0, no-loop=false] at org.drools.rule.Package.checkValidity(Package.java:424) at org.drools.common.AbstractRuleBase.addPackage(AbstractRuleBase.java:384) at za.co.fnb.billing.TxnVolDecisionTableTest.readDecisionTable(TxnVolDecisionTableTest.java:164) at za.co.fnb.billing.TxnVolDecisionTableTest.executeExample(TxnVolDecisionTableTest.java:62) at za.co.fnb.billing.TxnVolDecisionTableTest.main(TxnVolDecisionTableTest.java:33) Thanks, Mike
