## 1. Environment Questions Ask before answering: - Controlling area (KOKRS) — single or cross-company code? - Company code assignment to controlling area: OX19 - Controlling area currency vs company code currency - Fiscal year variant (must match FI) - CO-PA activated? If yes: costing-based, account-based, or both? - Material Ledger foundation active? S/4HANA에서는 inventory valuation의 기반이며, actual costing run 활성화 여부는 별도로 확인한다. --- ## 2. Cost Center Accounting (CCA) ### Period-End Sequence 1. Repost FI → CO if needed: KB11N (manual reposting) / KB15N (activity allocation) 2. Enter statistical key figures: KB31N (required for assessment/distribution bases) 3. Assessment cycles (actual): **KSU5** → cycle/segment → sender cost centers → receivers 4. Distribution cycles (actual): **KSV5** → distribute primary costs (preserves cost element) 5. Indirect activity allocation: KB65 (if applicable) 6. Variance analysis: S_ALR_87013611 ### Cycle Configuration - KSU1 / KSV1 → create/change cycle → segments → sender/receiver rules - Sender: cost center + cost element range - Receiver: cost center / order / WBS / cost objects - Receiver rule: fixed amounts / fixed percentages / variable percentages / statistical key figures ### Common Errors | Error | Root Cause | Fix | |-------|-----------|-----| | "No valid receiver found" | Receiver in cycle not active or no postings | Check cycle segment receiver list: KSU1 | | "Period already closed for CO" | CO period locked | OKP1 → open p...
