sorry there is a small correction in the earlier post... I - When I use 3 items 2 boxes....(this is wrong) item1 (4x4) --> box1 (5x5) item2 (4x4) --> box2 (5x5) item3 (4x4) --> box1 (5x5) II - When I use 2 item, result as follows...(this is correct) item1 (4x4) --> box1 (5x5) item2 (4x4) --> box2 (5x5) III - When I increase one more box....(this is correct too) item1 (4x4) --> box1 item2 (4x4) --> box2 item3 (4x4) --> box3 you can see the test I - it is over writing the first assignment and assign the new item there in the box 1, I unable to figure it out how to solve this problem, I suspect this can be done in the score calculation rules, the problem is I do not know how to implement to avoid the overwriting assignments. thanks, ----- with kind regards, -- View this message in context: http://drools.46999.n3.nabble.com/how-to-handle-the-overwrinting-values-i...
