how to use kanban +order

[mo ui]

I am currently learning JaamSim and have built a Kanban test model following an example.
Now I have added some additional conditions.

The process flow is:
OrderGen → Stn1 → KanBan_Conveyor → Stn2 → OutConveyor → EntitySink1

I am using the conveyor as the Kanban storage buffer. The Kanban is initially filled with 6 entities.
When Stn2 starts processing one entity, OrderGen generates a new entity to replenish the Kanban.

I realize my previous description may not have been clear enough. I've rebuilt the model, but now I'm encountering new issues:

1. Orders from the main order list are not displaying correctly in the format M1-6X, M1-9X, M2-6X, M2-9X.

2. I cannot properly connect S4 to QueueA, B, C, D. The S4 server's WaitQueue only accepts one input, and even when I try using an expression like:

text

choose( ([MainOrderQueue].obj(1).Order_M == "M1" ? 0 : 2) + ([MainOrderQueue].obj(1).Order_D == "_6X" ? 1 : 2), [QueueA], [QueueB], [QueueC], [QueueD] )

it doesn't work.

I would greatly appreciate if someone could help resolve these issues. Thank you!
