Which business process requires serial numbers?

Serial numbers in SAP S/4HANA Cloud Private Edition, Service are used to uniquely identify individual items, particularly in equipment and material tracking:

Tracking material items as pieces of equipment: This process requires serial numbers to monitor specific material items (e.g., spare parts or assets) as equipment throughout their lifecycle, including repairs or replacements. This is common in in-house repair or field service scenarios where serialized items are managed.

Installing and dismantling pieces of equipment: While equipment may have serial numbers, the process itself doesn’t inherently require them unless specified.

Creating a service order for an on-site service process: Serial numbers may be referenced but are not a requirement for the process.

Tracking the warranty of a technical object: Warranties can be tracked without serial numbers, though they may be used optionally.This aligns with SAP’s equipment management and logistics integration."Serial numbers are required to track material items as pieces of equipment in service and repair processes."
