Requirement
1. Business Objective
The organization requires accurate and transparent product cost calculations to support pricing decisions, profitability analysis, inventory valuation, and financial reporting. SAP Product Costing (CO-PC) must calculate standard, actual, and planned product costs in alignment with corporate finance policies.
2. In-Scope Processes
•
Material Standard Cost Estimation (CK11N/CK40N)
•
Cost Component Structure
•
Activity Type Planning (KP26)
•
Overhead Calculation via Costing Sheets
•
Work Center/Resource Rates
•
WIP Calculation and Settlement
•
Variance Calculation (KKS1/KKS2)
•
Material Ledger Actual Costing (Optional depending on requirement)
•
Integration with FI, CO, PP, MM, and SD
3. Functional Requirements
3.1 Master Data Requirements
•
The system must allow the creation and maintenance of:
•
Cost Component Structure (CCS)
•
Costing Variants for Standard, Planned, and Actual cost estimates
•
Overhead Groups and Costing Sheets
•
Activity Types with planned rates (labor, machine, setup)
•
Each material must have:
•
A costing lot size
•
Valid BOM and routing (or recipe/master recipe for process industries)
•
Assigned costing view in material master
3.2 Standard Cost Estimate
•
The system must calculate standard costs annually (or monthly if required) using CK40N for:
•
Raw materials (purchased)
•
Semi-finished goods
•
Finished goods
•
The cost estimate must:
•
Break down the cost into defined components (materials, labor, machine, overhead, subcontracting)
•
Pick valid BOM and routing data
•
Use activity rates from Cost Center Accounting (CCA)
•
The system must allow mass release of standard costs with automated FI revaluation postings (OBYC – PRD).
3.3 Overhead Calculation
•
The system must apply overheads based on:
•
Costing sheet (percentage-based or fixed rates)
•
Material origin indicator
•
Production plant
•
Overheads must be broken down by:
•
Material overhead
•
Production overhead
•
Administrative and sales overhead (optional)
3.4 Actual Costing / Material Ledger (If Required)
•
The system must capture actual price differences (PPV, exchange rate, freight, etc.).
•
Material Ledger must calculate:
•
Actual periodic unit price (PUP)
•
Leveling and revaluation of ending inventory
•
The system must generate FI/CO postings for variances and closing entries.
3.5 WIP & Variance Calculation
•
The system must calculate:
•
Work In Process (WIP) for orders not yet delivered
•
Variances for orders delivered (mix, qty, price, scrap, overhead variances)
•
The system must settle:
•
WIP to balance sheet accounts
•
Variances to P&L accounts
•
Settlement rules must be automatically derived based on material type and order type.
3.6 Integration Requirements
•
Posting of goods issue must update cost of goods manufactured using standard cost.
•
Production order confirmations must:
•
Post activity costs based on planned or actual activity rates
•
Capture scrap quantities and rework
•
Goods receipt from production must:
•
Credit production orders
•
Debit inventory at standard cost
•
In case of Material Ledger activation, system must revalue inventory and COGS at period-end closing.
4. Reporting Requirements
•
The system must provide:
•
Cost Component Reports (CK13N, CK11N)
•
Standard Cost Roll-up comparison
•
Production variances by plant, cost center, work center
•
WIP report by order
•
Actual vs Standard cost comparison
•
Reports must be accessible in SAP ECC/S4HANA, SAP Fiori, or BW (as defined).
5. Controls and Audit Requirements
•
Release of standard cost estimates must be restricted to authorized finance users.
•
Changes to BOM, routing, activity rates, costing sheets must be logged.
•
System must prevent cost estimate release if prerequisite master data is missing or inconsistent.
•
All FI postings related to product costing must flow to defined G/L accounts as per the chart of accounts.
6. Non-Functional Requirements
•
System must support multi-plant, multi-company costing.
•
Performance: Costing run (CK40N) must support batch execution and complete within defined batch window.
•
Compliance with IFRS/GAAP inventory valuation rules.
