Crane takes many items in the pallet

Hello esteemed teachers and colleagues in the Flexsim community. I am currently implementing a model using a crane to move items to processors. I am encountering a problem in using the crane to retrieve items from the pallets I have created earlier. I have tried several ways to reference objects within the pallets because I want the crane to retrieve multiple items, but I have only been able to do so when using the .first function to retrieve one item. I'm not sure if there is a way for me to achieve this, or if there is another approach where I can delete the pallet object when the forklift brings the pallet to the queue to simplify the problem. I would greatly appreciate any help from everyone. Thank you very much.

Hi @Thin Tn! Have you seen this tutorial? I think if you implemented it in your model it would solve your problem. Take a look at it and try it out and if you run into any other problems let me know and I can help you work through it!

crane_get_multi_item.fsmHello @Julie Weller ,thank you very much for responding. I tried applying that tutorial because you had suggested it to me before. I also thought using an array was the solution to my model, but perhaps I still didn't apply this part well. I tried again, but the crane still lifted the cluster instead of an array. I don't know if I missed a step or if I referenced the wrong object.

Okay! I went through your model, the first issue is that it stops at time 94.2 because you never release your operators, so make sure to release both your crane and machine. Then I deleted your query because it was making it so you could only pick up one item. You could maybe edit it now if you want something specific. The last and biggest issue was that your load was referencing the getitem label instead of Myitem (I also moved your Assign Labels activity to inside the first subflow. Here's the model, let me know if you can open it because I had to use FlexSim 19.1 instead of 19.0. Does that help a bit?
