SAP Product Costing – Finance Functional

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

1. 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)

2. 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

1. The system must calculate standard costs annually (or monthly if required) using CK40N for:

   • Raw materials (purchased)

   • Semi-finished goods

   • Finished goods

2. 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)

3. The system must allow mass release of standard costs with automated FI revaluation postings (OBYC – PRD).

3.3 Overhead Calculation

1. The system must apply overheads based on:

   • Costing sheet (percentage-based or fixed rates)

   • Material origin indicator

   • Production plant

2. Overheads must be broken down by:

   • Material overhead

   • Production overhead

   • Administrative and sales overhead (optional)

3.4 Actual Costing / Material Ledger (If Required)

1. The system must capture actual price differences (PPV, exchange rate, freight, etc.).

2. Material Ledger must calculate:

   • Actual periodic unit price (PUP)

   • Leveling and revaluation of ending inventory

3. The system must generate FI/CO postings for variances and closing entries.

3.5 WIP & Variance Calculation

1. The system must calculate:

   • Work In Process (WIP) for orders not yet delivered

   • Variances for orders delivered (mix, qty, price, scrap, overhead variances)

2. The system must settle:

   • WIP to balance sheet accounts

   • Variances to P&L accounts

3. Settlement rules must be automatically derived based on material type and order type.

3.6 Integration Requirements

1. Posting of goods issue must update cost of goods manufactured using standard cost.

2. Production order confirmations must:

   • Post activity costs based on planned or actual activity rates

   • Capture scrap quantities and rework

3. Goods receipt from production must:

   • Credit production orders

   • Debit inventory at standard cost

4. In case of Material Ledger activation, system must revalue inventory and COGS at period-end closing.

4. Reporting Requirements

1. 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

2. Reports must be accessible in SAP ECC/S4HANA, SAP Fiori, or BW (as defined).

5. Controls and Audit Requirements

1. Release of standard cost estimates must be restricted to authorized finance users.

2. Changes to BOM, routing, activity rates, costing sheets must be logged.

3. System must prevent cost estimate release if prerequisite master data is missing or inconsistent.

4. 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.
