Hi,

I have a event processing rule as follows

declare Sale

                @role(event)

end

rule "StoreABC"

                when

                                #conditions

                                Number( $TotalSalesAmount : intValue, intValue > 100)

                                from accumulate ( Sale($amount : amount, $quantity : quantity)

                                from entry-point StoreABC,sum($amount * $quantity))

                then

                                System.out.println("StoreABC sale exceeds 100…");

End

The POJO Sale has a attribute “String type;”. The above rule actually ignores the type, and does the accumulation for all types put together. Now I want the rule to fire successfully only when the TotalSalesAmount for _any_ given type exceeds 100.

And is it possible to access the “type” of Sale whose sales exceeded 100, in the “Then” clause ?

Example:

Lets say the input events are  as below (Triplets – Type, Quantity and Amount)

1. Apple , 10, 5

2. Orange, 10, 6

3. Banana,  20, 4

4. Orange, 10, 5

5. Apple, 2, 5

Now in the above rule, the event fires after Event 2 since the total sales is > 100. However I want the rule to fire after Event 4 since at that point the sale of one particular item, viz. “Orange” exceeds 100 in this store. In the “THEN” clause of the rules, I also want access to a variable that indicates that it was “Orange” whose sale exceeded 100 in this store.

Is this possible in Drools Fusion ? If yes, can you please let me know the changes to be made to the above rule ?

Thanks
