Production variance analysis in SAP S/4HANA helps explain differences between manufacturing costs and a defined cost baseline. This chapter-by-chapter overview of John Jordan and Janet Salmon's book covers planning, standard cost estimates, actual costs, period-end processing, scrap, reporting, and event-based production accounting.

Introduction
Production Variance Analysis in SAP S/4HANA, by John Jordan and Janet Salmon, explains how manufacturing master data, cost planning, actual postings, and closing processes fit together. This overview describes the edition published by SAP PRESS in 2023.
The examples reflect the book's publication-era systems. Chapters 1–6 cover conventional product costing and period-end processes; Chapter 7 introduces event-based production cost posting and universal parallel accounting. Availability and implementation details depend on your S/4HANA edition, release, and configuration.
For a broader process overview, see our SAP Product Cost Controlling guide.

Chapter 1 Initial Planning
We provide an overview and details of the planning process with SAP Sales and Operations Planning and SAP Integrated Business Planning IBP to set the baseline for variance analysis.
Figure 1: Sales and Operations Planning
We examine sales and operations planning (S&OP), as shown in Figure 1. We also examine long-term planning to determine the raw materials to be purchased and the available manufacturing capacity to be reserved.
The book discusses classic Sales and Operations Planning alongside SAP Integrated Business Planning for Supply Chain (SAP IBP). Review the supported planning tools and migration approach for your landscape rather than assuming that SAP IBP reproduces every classic S&OP feature.
A production version links the relevant BOM alternative and routing or recipe for a material. Multiple production versions can represent alternative manufacturing methods; the selected version influences the quantity structure used in planning and costing.
We look at cost center planning and how to combine the planned expenses and activity usage with setting the plan activity rates for activities.
Chapter 2 Cost Estimates
We introduce master data and explain the material master, BOM, routing, and work center to create cost estimates, as shown in Figure 2.
We present the role of the costing sheet in determining the overhead to be applied to your raw materials and manufacturing activities. We also discuss the configuration for the cost components and the costing variant.
Figure 2: Cost Estimate BOM and Routing
We then provide instructions for creating and releasing a cost estimate to set the standard price for a single material. We introduce the costing run to develop the standard costs for all materials in a plant. Where multiple production options exist for a material, we explain how to use a mixed cost estimate to combine different production or procurement alternatives to deliver one standard cost.
Chapter 3 Actual Costs
We introduce the Universal Journal and its impact on primary and secondary costs. We walk through the steps on the shop floor, such as production order and process order activity confirmation and component goods issues, that result in actual postings, as shown in Figure 3.
One of the fundamental changes in SAP S/4HANA is that the work center and operation are now part of the data structure for variance analysis.
Figure 3: Production Order Actual Costs During Goods Issue
The book introduces two SAP Fiori analytical apps:
- Production Cost Analysis (ID F1780)
- Analyze Costs by Work Center/Operation (ID F3331)
See our detailed guide to SAP Fiori apps for manufacturing variance analysis. Analytical cost differences should be distinguished from accounting postings for WIP and settlement.
Chapter 4 Period-End Processing
We explain variance calculation and the categories used to analyze production cost differences. We also discuss related cost center and purchase price variances, which should be distinguished from manufacturing-order variance categories.
We include detailed examples to help you easily understand period-end processing, including overhead, Work in Process WIP, variance calculation, and settlement.
Figure 4: Variance Splitting Profile
Figure 4 illustrates a variance splitting profile. We also explain how actual costing with SAP Material Ledger can allocate eligible purchasing and production differences through the value chain.
Chapter 5 Scrap Variance
We walk through the scrap calculation in detail, including:
- Assembly Scrap
- Component Scrap
- Operation Scrap
Figure 5: Component Scrap Increases Component Input Quantity
We explain the types of scrap, including Assembly Scrap, Component Scrap, and Operation Scrap, and their interaction as shown in Figure 5.
Chapter 6 Reporting
We explain the impact of production variances on product profitability and discuss the options for analyzing data in detail.
Figure 6 : Standard Cost Center Reporting
We look at standard reports in detail, including Cost Center Reporting as shown in Figure 6.
We analyze summarization reporting, including product drilldown reports.
We explore both classic reports and tools and SAP Fiori apps.
Chapter 7 Future Direction of Variance Analysis
Chapter 7 introduces event-based production accounting, illustrated in Figure 7. In supported scenarios, business events trigger WIP and variance postings during the production cycle. For manufacturing orders, final goods receipt or technical completion can clear WIP and trigger variance settlement, depending on the process and configuration.
Figure 7: Event-Based Production Cost Cycle
Chapter 7 explains scrap and mixed price variances.
The book discusses SAP S/4HANA Cloud scope item 3F0 and SAP S/4HANA 2022 options with universal parallel accounting. For current Public Edition process details, see SAP Help: Event-Based Production Cost Posting. Do not assume identical functions or activation requirements across editions.

Glossary
Actual Costs
Costs recorded through business transactions such as goods issues, activity allocations, and overhead postings. Distinguish order debits from credits when reviewing balances.
Actual Costing
A Material Ledger process that determines actual material costs and allocates eligible price differences to inventory and consumption according to the configured process.
Assembly Scrap
Planned loss in assembly output that increases the quantities required to achieve the expected usable output.
Component Scrap
Planned loss for an individual component that increases its required input quantity.
Production Version
Master data linking a material to a specific BOM alternative and routing or recipe for a defined validity period and lot-size range.
Standard Cost Estimate
A material cost estimate that can establish the standard price through marking and release under the applicable valuation settings.
Target Costs
Expected costs for actual output, calculated using the relevant cost baseline and costing rules.
Variance Categories
Classifications that explain cost differences, such as input price, input quantity, resource usage, and other variances. Available categories depend on the costing scenario.
Variance Splitting
A configured breakdown of production variances for accounting and reporting. It is distinct from calculating a simple actual/target difference.
Work in Process (WIP)
The valuation of unfinished production under the configured accounting method. WIP is not automatically equal to a difference displayed in an analytical report.
Settlement
The process of transferring costs, WIP, or variances from a cost object to the relevant receivers according to the accounting process and configuration.
Event-Based Production Costing
An accounting approach in which relevant production business events trigger WIP and variance postings, with behavior determined by the supported scenario and settings.
