Hi,
I dont know how to solve the following problem: I have a model where rack must be emptied from time to time. I have two lists that are dynamically changed. In the first one (ListA) are items currently located in the rack. In second (ListB) are item IDs that are temporarily reserved (but this may change over time). I would like to do in ProcessFlow an operation after which I will have a list of items needed to be retrieved from the rack (those that are on ListA and are not on ListB). Or loops, then it will in turn compare the positions in the listA and the list B. (values from both lists can not be pulled - they must remain there) Is it possible to quickly compare both lists and generate list of needed items?
