We want to receive labels with serial numbers, but we do not want to register these serial numbers during purchase order receipt or keep them in inventory.
The label is only used when a second serial number is required for the end product (as a customer-selectable CTO option).

If this label is included in the product structure/shop order materials, the system should force serial number registration when the part is backflushed / issued into the tracked structure.

With the current part-level serial tracking settings, I cannot find the right solution.
Has anyone solved this requirement?
