Allocation methods

Listen to this lesson
Most costs do not land where they belong. Rent, utilities, plant IT, the canteen and the maintenance crew are posted to service cost centers, but the products and customers that consume those services sit elsewhere. Allocation is how controlling moves those costs to the cost centers, orders and market segments that caused them. SAP S/4HANA offers three main ways to do it, and the difference between them is not academic: it decides which accounts the receiver sees, which reports show the cost, and what a tester should expect.
Distribution, assessment and activity allocation
Distribution moves primary costs from a sender cost center to receivers and keeps the original account. If IT Services spent $18,000 on software licences, the receivers see $18,000 on the software licence account. Assessment (SAP Learning also calls it overhead allocation) moves primary and secondary costs together and posts them under one assessment account, a secondary cost account with cost element category 42. The receiver sees "facilities assessment $60,000" and nothing about the rent, power and cleaning inside it. Activity allocation is different again: the sender provides a measurable service, such as assembly labor hours, and the receiver is charged quantity times a rate, using a secondary cost account with category 43.
| Distribution | Assessment | Direct activity allocation | |
|---|---|---|---|
| What moves | Primary costs only | Primary and secondary costs | A quantity of activity, valued at a rate |
| Account on the receiver | The original primary account | One assessment account (category 42) | An activity allocation account (category 43) |
| Typical receivers | Cost centers, WBS elements | Cost centers, WBS elements, profit centers, market segments | Cost centers, orders, WBS elements |
| Driver | Percentages, amounts or statistical key figures | Percentages, amounts or statistical key figures | Recorded quantities (hours, machine hours) |
| When to use | Receiver needs to see the cost composition | Receiver only needs the total | Service is measurable per receiver |
A simple rule of thumb comes from SAP's own training: choose distribution when the receiver needs to see the cost composition, and assessment when the composition does not matter to the receiver and a single line keeps reports simpler. Choose activity allocation when you can measure the service per receiver, because then the charge follows real consumption rather than a key.
Activity allocation needs a rate. Cost rates for activity types are usually planned once a year per cost center: how much Detroit Assembly charges per labor hour, for example. During the year, orders are charged at that plan rate. At period end, an optional actual activity price calculation can work out what the hour really cost from the cost center's actual costs and quantities, and orders can be revalued at that actual price. Whether Contoso revalues is a design decision with the same trade-offs as actual costing: more accurate product costs against more close steps. At go-live, Contoso charges at plan rates and analyzes the under- or over-absorption that remains on Assembly and Machining.
Contoso's allocation design
Contoso's Detroit plant has three service cost centers and three cost centers that consume their services. The names and numbers below are the ones used throughout this course.
| Cost center | Role | How its costs move |
|---|---|---|
| 17101105 Detroit Facilities | Rent, power, cleaning, building maintenance | Assessment by floor space (statistical key figure, square feet) |
| 17101301 IT Services | Software licences, network, devices | Distribution of licence and network accounts by headcount |
| 17101101 Detroit Assembly | Production: alternator assembly | Activity type ASSYHR (assembly labor hour), plan rate $52 |
| 17101104 Detroit Machining | Production: housing machining | Activity type MACHHR (machine hour), plan rate $96 |
| 17101106 Detroit Warehouse | Receiving, storage, picking | Credited by material overhead on production orders |
Contoso Detroit (company code 1710, controlling area A000): service and production cost centers.
- Primary postingsInvoices, payroll and depreciation post to the service and production cost centers
- DistributionIT Services licence costs spread to Assembly, Machining and Warehouse on their original accounts
- AssessmentFacilities costs move to the other cost centers by floor space on one assessment account
- Activity allocationAssembly and Machining charge production orders for hours used
- Overhead and settlementOrders receive overhead, then settle to inventory and variances
What would you do?
Grace asks why the Assembly cost center report shows "Facilities assessment $60,000" but no electricity cost, while the energy manager wants to see electricity per production area. What should the controlling team propose?
- Distribution moves primary costs and keeps the original account on the receiver.
- Assessment moves primary and secondary costs under one category 42 assessment account.
- Direct activity allocation charges quantity times rate on a category 43 account.
- Pick the method by what the receiver needs to see and whether consumption can be measured.
