Hi, I changed some information about slot number and in the first part (storage) everything is correct but in the second part (pick from list) the operator didn't go the the rack. Where is the problem. Thank you very much.

Query of "Pull from List" considers a field "Slot" not present in the list "Inventories_list".

Infact if label field "Slot" is added to List, the model works and operator goes to right rack.

Attached you will find themodel with the additions.

Hi,

in the "Pull From List" it's necessary to updated query to choose right rack (WHERE Type = puller.Type AND Rack = puller.Rack).

In particular, the field "Rack" in "Inventories_list" is a object.So in the section "Pick Creation" of process flow, when you assign labels to picks, token.Rack has to be a link to a Object, using function Model.find(...), as you used in the "Create Object" code.

In the simulation it is impossible to satisfy the first picking request because the requested type is not present in the desired rack.

Attached you will find the model with the additions.


Note: You can consider to use the new "StorageSystem" to improve warehouses management.

Thanks alfredo. I ask you two last thing. The first one: How can I model the file if I want that the operator picks, in the same pallet, only items that have the same label "Type"? second thing: how can i change the 3d shape of the box in rack 3,4,5 whitout modify the 3d shape in rack 1 and 2? i tried with on entry triggers but it doesn't work. Thank you so much.

Sorry Luca, I'm not sure I understand the first question.
About the second you can use function Flowitem by Case of "Create Object" activity.
For that I have added a label "nrRack" to pallet.

The entry trigger of racks doesn't work because the process creates directly box into pallets and not into to racks.

It's necessary that when the label "type" are the same, even if the row in the picking list are different, the items must be load in the same pallet and then the operator can change pallet to pick another box with different label "type". Thank you very much
