I’m using drools in order to make a decision on whether to purchase certain stock items or dispose of stock items. Our system takes a stock import and feeds the values into drools by inserting an object into the knowledge session; this object is mapped to the human task as a variable. If a rule passes it will create a human task to purchase stock for that item. The user then purchases more stock and completes the human task. Our system may import the same stock file and feed the values into drools again, I want to ensure that a task isn’t created to purchase that stock item again, is there any way of searching previously completed tasks by the object mapped as a variable to the human task.
