Serial Numbers in Production Orders 
Use
It is possible to assign material numbers for individual pieces of material that are to be produced or refurbished when creating, changing or releasing production and refurbishment orders. The serial numbers always refer to the order item.
The serial numbers that are assigned to the production or refurbishment order are transferred to the document on goods receipt.
Integration
In order to use the serialization functionality in production orders, you must have implemented the Production planning and control component, and for refurbishment orders, the Plant maintenance component.
Prerequisites
A serial number profile with the procedures PPAU and PPRL must be entered in the material master record:

If the assignment of serial numbers is to be performed differently for production orders and refurbishment orders, you must create different serial number profiles. You must then assign these profiles to the respective finished product or refurbishment material.
Features

When printing shop papers you can also print a label with barcode for each serial number.
If a production order is created with reference to a sales order item within the framework of make-to-order production, the system proposes all serial numbers assigned to this item in the production order.
