Hi, For below rule RCVRCOUNTRY == IRAQ,IRAN SNDRCOUNTRY == US,CAN,UK AMOUNT > 3000 i have to compile the drl with this m: (TransactionBean(RCVRCOUNTRY == "IRAQ", SNDRCOUNTRY == "US", AMOUNT > "3000")) or (TransactionBean(RCVRCOUNTRY == "IRAQ", SNDRCOUNTRY == "UK", AMOUNT > "3000")) or (TransactionBean(RCVRCOUNTRY == "IRAQ", SNDRCOUNTRY == "CAN", AMOUNT > "3000")) or (TransactionBean(RCVRCOUNTRY == "IRAN", SNDRCOUNTRY == "US", AMOUNT > "3000")) or (TransactionBean(RCVRCOUNTRY == "IRAN", SNDRCOUNTRY == "UK", AMOUNT > "3000")) or (TransactionBean(RCVRCOUNTRY == "IRAN", SNDRCOUNTRY == "CAN", AMOUNT > "3000")) Is there any other easier / better way to express this as a valid DRL? -- View this message in context: http://www.nabble.com/Problem-with-And-and-Or-operator-tf2940364.html#a82...
