SAP S/4HANA Asset Management scope items explained (4HH, 4HI, 4WM, 4VT, 43R)

SAP standard Asset Management is organised around a family of scope items, each representing a different maintenance process with its own governance intensity. Choosing the right scope item is the first design decision in an EAM project — it shapes which Fiori apps are relevant, how status and approval logic behave, and how much planning discipline the organisation needs. Start here, before designing custom order types.

The scope-item family

• 4HH — Reactive maintenance. Breakdown-to-repair, corrective work. Urgency first. The phase model runs as the process narrative from request to close.
• 4HI — Proactive maintenance. Planned and recurring work driven by maintenance plans. Compliance first — recurring obligations and preventive strategy.
• 4WM — Operational and overhead maintenance. Routine internal work that doesn't need the same planning depth. Visibility first.
• 4VT — Improvement maintenance. Engineering-change-style work where maintenance overlaps with change control. Change control first.
• 43R — Resource Scheduling. Adds capacity and dispatching discipline on top. Resource balance first. (See Resource Scheduling (RSH).)

How to choose

Map the business scenario to the process family before discussing design or customisations:

• Breakdown-to-order flow → 4HH.
• Planned / recurring work → 4HI.
• Routine overhead work → 4WM.
• Maintenance that overlaps with engineering change → 4VT.
• Capacity and dispatch must be visible → add 43R.

The process family changes governance and app usage more than the business objective does — which is why it comes first.

A common project anti-pattern

Starting from custom order types or local status names usually hides the real issue: process-family ambiguity. Don't copy every historical order type into S/4HANA. Keep only the distinctions that drive a materially different control model — every extra order type should mean a different way of controlling the work, not just a different label.

Common questions

Can one organisation use several scope items? Yes — most do. The point is to assign each type of work to the process family that fits, rather than forcing everything through one custom flow.

Where does the phase model fit? The phase model is the common process narrative across the reactive (4HH) and proactive (4HI) processes.

Is 43R always needed? No — only when capacity balancing and dispatch are a real, recurring problem.
