Serial required in POS view

Hey all,
When I input serial no in search item, the system adds it in the cart.
But when I pay the bill, the system can not generate the invoice and warning:
Serial Nos Required for Serialized.
Is it a bug?
I am using erpnext version:

ERPNext: v11.1.20 (master)

ERPNext Factory App: v0.0.1 (master)

ERPNext POSO App: v0.0.1 (master)

Frappe Framework: v11.1.21 (master)

Please help me this problem.

Disable serial tracking, if not allowed duplicate the item and disable the old one.

I think it’s:

Item List > TestSerial > Batch and Serials Sections

@adam26d Thnaks for your reply, but i need control all items by serial.

But in the POS view, I don’t know how to automatic get the serial number with that item.
In the ver10. I can do it easy.
Please help me in this problem. I don’t know where to setting.
When I sale this item by sale invoice and delivery note, it easy to put serial in the invoice

I have the same problem with v12.

I have added serial and batch.
