Hi,

How do I use <otherwise> in Decision Tables created using Eclipse (Excel
Spreadsheets). I have created a rule where I have provided "<otherwise>" as
a criteria but its been taken as the value of the parameter instead of
creating a separate rule with the "not" clause. I am providing the
screenshot of the decision table as well as the rules generated by Drools.

I would much appreciate if someone can advise on how I can use <otherwise>
in my rules.

Drools conversion to ".drl" below (Rule Flight_Type_Rules_15 shows
<otherwise> being used as parameter valUE):

DRL is :: package com.test.BasicDTRules;
//generated from Decision Table
import java.util.Date;
import com.test.Flight;
// rule values at C11, header at C6
rule "Flight Type Rules_11"
when
flight : Flight(flightNumber >= "0001", flightNumber <= "1000",
airlineCode == "BA")
then
flight.setFlightType("SH");
flight.setValid(true);
System.out.println("Row 1");
end

// rule values at C12, header at C6
rule "Flight Type Rules_12"
when
flight : Flight(flightNumber >= "0001", flightNumber <= "1000",
airlineCode == "AA")
then
flight.setFlightType("SH");
flight.setValid(true);
System.out.println("Row 2");
end

// rule values at C13, header at C6
rule "Flight Type Rules_13"
when
flight : Flight(flightNumber >= "1001", flightNumber <= "2500",
airlineCode == "VG")
then
flight.setFlightType("LH");
flight.setValid(true);
System.out.println("Row 3");
end

// rule values at C14, header at C6
rule "Flight Type Rules_14"
when
flight : Flight(flightNumber >= "1001", flightNumber <= "2500",
airlineCode == "AA")
then
flight.setFlightType("550");
flight.setValid(true);
System.out.println("Row 4");
end

// rule values at C15, header at C6
rule "Flight Type Rules_15"
when
flight : Flight(flightNumber >= "2501", flightNumber <= "9999",
airlineCode == "<otherwise>")
then
flight.setFlightType("Invalid");
flight.setValid(false);
System.out.println("Row 5");
end

Thanks,
dme
