Hi,
The business requirements are as follows.
We have 3 rules which need to be fired depending upon the criteria which
will be met. We have an order object which has various orderline items and
the following business rules need to be executed depending upon the inserted
facts.
• If a particular item is on discount, the discount % is applied to the line
item.
• If the quantity for a particular item is greater than 10, an added 10%
discount is given for the order.
• If the total order amount is greater than 1000, then an additional 5%
discount is given on the order.
The above rules need to be executed at the same time.
In This case i tryed all the conditions it's working fine.But,
rule "Apply 5% discount if Total Price greater than 1000" is not fired.
package com.sample.orderItem
import com.sample.orderItem.DiscountDetails
import com.sample.orderItem.ItemQuantity
import com.sample.orderItem.PriceCal
import com.sample.orderItem.PriceDetails
expander Sample.dsl
rule "Purchase Item"
salience 10
when
$p:PriceCal(itemName:itemName, quantity:quantity,
discountPer:discountPer, itemprice:itemprice, totalprice:totalprice,
totalPriceAfterDiscount:totalPriceAfterDiscount)
then
System.out.println("Purchased Item : " +itemName );
System.out.println("Itemprice Prise : " +itemprice);
System.out.println("Itemprice quantity : " +quantity);
System.out.println("discountPer : " +discountPer);
end
rule "Item Discountper equal to null"
salience 10
when
$p:PriceCal(itemName:itemName, quantity:quantity,
discountPer:discountPer, itemprice:itemprice, totalprice:totalprice,
totalPriceAfterDiscount:totalPriceAfterDiscount)
eval($p.getDiscountPer() == null)
then
$p.setTotalprice(totalprice+itemprice*quantity);
System.out.println("totalprice non Disc : "
+$p.getTotalprice()
);
end
rule "Item Discountper not equal to null"
salience 10
when
$p:PriceCal(itemName:itemName, quantity:quantity,
discountPer:discountPer, itemprice:itemprice, totalprice:totalprice,
totalPriceAfterDiscount:totalPriceAfterDiscount)
eval($p.getDiscountPer() != null)
then
$p.setItemprice(itemprice*(100-Integer.parseInt(discountPer))/100);
System.out.println("default discountl: "+$p.getItemprice());
$p.setTotalprice(totalprice+$p.getItemprice()*quantity);
System.out.println("Totalprice : " +$p.getTotalprice() );
end
rule "Apply 10% discount if quantity greater than 10"
when
$p:PriceCal(itemName:itemName, quantity:quantity,
discountPer:discountPer, itemprice:itemprice, totalprice:totalprice,
totalPriceAfterDiscount:totalPriceAfterDiscount)
eval($p.getQuantity() > 10)
then
$p.setTotalprice($p.getTotalprice()*0.90);
System.out.println("Apply 10% discount if quantity greater than 10
:
" +$p.getTotalprice() );
end
rule "Apply 5% discount if Total Price greater than 1000"
when
$p:PriceCal(itemName:itemName, quantity:quantity,
discountPer:discountPer, itemprice:itemprice, totalprice:totalprice,
totalPriceAfterDiscount:totalPriceAfterDiscount)
eval($p.getTotalprice() > 1000)
then
$p.setTotalprice($p.getTotalprice()*0.95);
System.out.println("Apply 5% discount if Total Price greater than 1000
: " +$p.getTotalprice() );
end
Result:
-------
Purchased Item : abc
Itemprice Prise : 100.0
Itemprice quantity : 13
discountPer : 5
default discount l: 95.0
Totalprice : 1235.0
Apply 10% discount if quantity greater than 10 : 1111.5
please give me proper suggestion of this.
thanks,
manyasri.

Is this supposed to react to the total price value being set in the other rules? If so
you need to notify the engine that the object has been updated. Pass the object to
update() in the right hand side of the rules where it's modified.
