Task error when picker tries to travel at the correct item to pick

Hello dear community,

I am having trouble creating a picking process for my warehouse model. In this model boxes are created on pallets and then the pallets are stored at slots in racks that matches their sku. I am trying ro create random picking orders, based on the 2019 warehouse model that is uploaded, but when my picker is to travel at the correct item to pick, a task error appears. I think i am making a mistake when i search for the item that matches the sku or when i record the item onto the parent. I would really appreciate any of your help on the matter. Also, is there a way to determine the percentage of ABC types that each order is going to have? Thank you in advance.

Best regards,

Jim

Your items all point to the model:

The item you find will be the pallet.

You should not mark it as outbound since you're picking items from it, not removing the pallet.

You will need to ensure yourself that you do not add picks that have already been earmarked for picking. This is a limitation of the storage system at the moment - it only tracks containers (pallets) not their content.

Thank you very much @Jason Lightfoot for your answer! I tried to adjust to that further by assigning a label as box that looks for the items inside the pallet. What changes do you suggest to be made in order for this logic to work or is it not possible the way it is set up? If it does work, the limitation of the storage system wont allow for a query in which when a pallet empties the reach trucks throw it away and replace it with a new one? Thank you again in advance.

Yes when the pallet is empty (or about to be emptied) mark it as outbound and remove it.

You could track a label 'availableToPickQty' on the pallet - and decrement it whenever you choose to take a number of items from it. Then I would only decide exactly which items at the point of picking.

Thank you again @Jason Lightfoot for the advice. But i still havent figured out, is there a way to make the picker travel at the pallets, with this logic, without the task error or something different, like a list, should be used? I unmarked it as outbound and tried to reference to the subnodes of the pallet but i kept getting errors.Thank you so much for your time.
