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.
