Why：Generating a lot number here is the start of the entire outsourcing trail — Overmolding Return, NPG FQC, and FG in/out all key off this lot. Once generated it can't be undone, so verify the pool total and shipping quantity before submitting.
Check the current 2F pool total (quantity available to ship).
Enter the quantity to ship — can't exceed the pool total.
Enter the operator ID and submit.
The system generates a new lot number (format: OM+date+2 digits) and deducts it from the 2F pool.
Record or print the lot number and hand it to the outsourcing vendor.
