[rules-users] Does Drools Fusion support "Group By" clause ?

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 Kiran
