Configuring and Creating Serial Numbers

1. A faulty piece of equipment must be dismantled and transferred to the warehouse. A prerequisite for this function is that the equipment is serialized. When equipment is serialized, the tab page for serialization data is activated and a serial number links the equipment to a material.

   The defective piece of equipment is dismantled and transferred to the warehouse for refurbishment. You have a function for installing and dismantling equipment with simultaneous goods movement.

2. The defective, serialized equipment needs to be refurbished. The serial number links the equipment with a material with condition-based evaluation. A material is broken down into different partial stocks by a condition-based evaluation. There are batches "as new" (C1), "refurbished" (C2), and "faulty" (C3).

3. The refurbished piece of equipment is returned to the warehouse using the linked material and serial numbers.

4. In one step, you can remove a piece of equipment from a storage location and install it at another piece of equipment or functional location.

Serialization thus enables inventory management of pieces of equipment.

If a material piece of equipment is to be uniquely identifiable in terms of inventory management, a serial number profile must be entered in the material master. The serial number profile defines the business operations for which serial numbers are mandatory.

A serial number profile is data stored under a four-figure key that defines the conditions and operations for the assignment of serial numbers for material items.

Serial number profiles are defined during system configuration in Customizing of Plant Maintenance and Customer Service. You can define the following parameters:

• Business transactions for which a check is performed
• Existence requirement for serial numbers
• Automatic creation of the serial number
• Existence requirement for pieces of equipment
• Equipment category

There are several SAP Fiori Apps available to maintain Serial Numbers in simplified way.

You can use this app to:

• Create, change, and display a list of serial numbers assigned to a material, plant, storage location, stock type, special stock, or batch.
• Search for a specific serial number.
• Export a list of serial numbers.
• Filter, sort, and group your results list according to your needs.
