how to separate the items according to the rack slot space

I want to know how to separate the sub-items from the separater according to the slot space of the rack.

The status picture and my issue model is followed.

PickingItems_StorableSlots.fsm

The slot assignment strategy is Bay, Level, SlotID with space. So I customed a little like picture.

But the separator unpacking quantity should be changed according to the rack slot space to be storable.

I found using setvarnum(...splitquantity...) command in Separator not valid. How can I do it?

Using Process Flow? if so how to do? or another method?

The container with remaining contents should be separated to the queue(port #1).

Thanks.

Separator and Combiner are numb objects. They collect or divert items by number. That’s there only purpose. It seems they are more intelligent to consider attributes but they are not. If you want to act on conditions you have to get to a decision on entry of items. It is like a forecast.
This said you have to query slots on entry of your separator. The number of available slots or current amount of packed items set a label at your separator, which gets evaluated in unpack quantity. You assign queried slots on entry right away, because on process finish circumstances might have changed. The result of your query is an array. You can use methods pop or shift to return a slot from your array to assign a slot to an storage item in a loop structure.

Hi. Joerg. Thank you.

I customed on Entry of separator as followed;

Object current = ownerobject(c);

Object item = param(1);

int port = param(2);

{ // ************* PickOption Start ************* //

Storage.Object StorageObject = Model.find("Rack1");

Storage.Item StorageItem = Storage.Item(item);

Variant bayID = item.Type;

Variant levelID = item.LevelID;

Variant slotID = item.SlotID;

Storage.Slot slot = StorageObject.getSlot(bayID, levelID, slotID);

current.Quantity = slot.slotItems.length; // unpacking Quantity

// setvarnum(current, )

But the unpacking 'Quantity' ('splitquantity') can't changed.

Other method need?

Hello @David Seo, I call assign slot strategy in on Entry of separator. Previously I added another return statement in this function to identify an unassigned slot. By calling this nodefunction on each item in the tote I get a number of items to unpack. I store this number in a label aand read the value to unpack items.

Array parts = item.subnodes.toArray();
int elm = parts.length;
for (elm; elm > 0;elm--)
{
  if(nodefunction(Model.find("/Rack1>variables/slotAssignment"),parts[elm])){
    elm++;
    break;
  }
}
current.unpacQty = parts.length-elm;

Thanks very much. I do not know 'nodefunction' command.

You could copy the code from a node and execute it. nodefunction replaces only some coding, that is all.
