BOM usage 4 (Plant Maintenance)in SAP S/4HANA Cloud Private Edition, Service is designed for maintenance processes, listing components (e.g., spare parts) for technical objects. The correct benefits arespare parts planning in task list (C)andspare parts planning in service order (D). Let’s break this down thoroughly.

What is BOM Usage 4?

A BOM with usage 4 is linked to equipment or functional locations, defining parts needed for maintenance (e.g., bolts, filters). It’s maintained in transactions like IB01/IB02.

Spare parts planning in task list (C):When a task list (e.g., for pump maintenance) references a technical object with a BOM usage 4, the BOM’s components are pulled into the task list operations as planned spare parts. This ensures materials are reserved or ordered in advance. For example, Operation 0010 might list "Gasket" from the BOM.

Spare parts planning in service order (D):A service order linked to a technical object inherits the BOM usage 4 components, enabling spare parts planning directly in the order. This supports reservations or goods issues (e.g., via IW31/IW32).

Why Not the Others?

Spare parts planning in service order template (A):Service order templates define structure, not BOM-linked planning; BOM usage 4 applies to execution objects (orders, task lists).

Structuring of technical assets (B):BOMs describe components, not the hierarchical structure (handled by functional locations or equipment hierarchies).

Real-World Benefit:

A pump’s BOM (usage 4) lists "Seal" and "Bearing." A task list or service order automatically plans these, reducing downtime by ensuring availability.

"BOMs with usage 4 enable spare parts planning in task lists and service orders, enhancing maintenance efficiency."
