I have a TE that picks items 1s, 2s and 3s but when he picks 3s (Del) first and he has 2 (Live) or 3 (Pre) available, he has to get a new container to place items 1 or 3 on it and drop that container, then he can continue to pick in his original container if he still has capacity in that container (in my example 4). Also in the model if he does not have any pick available I directed to drop the container to a designated location (1s and 2s to CPU drop and 3s to "Del Drop"). In other words items 1 and 2 can share a container but not 3's when the container is drop. Also the priority is to pull 1s first , 2s second and last 3s. Right now in my model I can't quite identify the right container to place the items.
