Explanation

📌 KEY POINTS
✅ The company code is the legal entity for which a complete set of books (balance sheet and P&L) is produced.
✅ A chart of accounts lists GL accounts; one chart can serve many company codes for consistent reporting.
✅ GL accounts have a chart-of-accounts part (name, type, group) and a company-code part (currency, open item, field status).
✅ Fiscal year variant and posting period variant decide when you can post.
⚠️ In S/4HANA cost elements are GL accounts — the account type (balance sheet, nonoperating, primary or secondary cost) is chosen at creation and matters for CO.

▶ WHAT THIS SERIES COVERS
Part 1: Foundations — organization, chart of accounts, master data
Part 2: Posting flow, integration and the universal journal

━━━━━━━━━━━━━━━━━━━━
▶ 1. COMPANY CODE AND LEDGER

Company code = legal entity with its own currency and financial statements.
Leading ledger 0L holds the main accounting principle; other ledgers for parallel valuation.

━━━━━━━━━━━━━━━━━━━━
▶ 2. CHART OF ACCOUNTS

Operational chart used for daily postings; optional group and country charts.
Assignment company code → chart of accounts.

━━━━━━━━━━━━━━━━━━━━
▶ 3. GL ACCOUNT MASTER DATA

Chart level: account number, type, account group, texts.
Company code level: currency, tax category, open item / line item display, sort key, field status group.
Account groups control number ranges and screen fields.

━━━━━━━━━━━━━━━━━━━━
▶ 4. FISCAL YEAR AND POSTING PERIODS

Fiscal year variant: 12 periods + special periods for year-end.
Posting period variant: which periods are open per account type.

━━━━━━━━━━━━━━━━━━━━
▶ 5. CONTROLS

Field status groups decide which fields are required/optional/suppressed.
Retained earnings account carries P&L balances into the new year.

━━━━━━━━━━━━━━━━━━━━
▶ STEP BY STEP

Review company code and its assigned chart of accounts.
Create a GL account (balance sheet) and a primary cost account in FS00.
Open the current period in the posting period variant.
Post a test entry and display the account balance.

✅ CHECKPOINT: you can explain every field you maintained and why the posting succeeded.

Code example

ABAP Code

Real project scenario

A newly onboarded FI consultant on a global rollout created revenue accounts as nonoperating income, so CO never received revenue and margin reports were empty. Changing the design to "primary costs or revenue" before go-live (after reversing test postings) fixed it; the team added an account-type review step to the master data checklist.

Common mistakes

Treating the company code as a plant or site.
Creating accounts without an account group strategy.
Wrong S/4HANA account type (CO impact).
Forgetting open item management on clearing accounts.
Opening all periods permanently.

Best practices

One operational chart of accounts for the group.
Define account groups with number ranges.
Decide account type with controlling.
Use open item management for clearing accounts.
Open and close periods deliberately each month.

Interview angle

Questions: "What is a company code?", "What are the two levels of a GL account?", "What changes for cost elements in S/4HANA?", "How do you control posting periods?"
Strong answer: company code as legal entity, chart of accounts assignment, chart/company-code master data, account types, fiscal year and period variants, field status.

Practice this lesson

Quick check

1. Interviewers frequently ask candidates to explain, in their own words, what the Universal Journal changed and why it matters operationally (real-time FI-CO alignment, single source of truth, elimination of reconciliation runs) - strong answ. In the General Ledger context, which answer shows the strongest practical judgment?

2. A GL account has settings at two levels. Which setting belongs to the company code level?

3. A team wants to create revenue accounts as "nonoperating income" to save time. What is the consequence in S/4HANA?

Interview questions

1. A vendor invoice for a purchase order is received in USD, while the PO was created in EUR, and the company code's local currency is GBP. Walk through how SAP calculates and posts the currency amounts and any exchange rate differences to the GL.

Answer it in your own words first, then compare.

2. During year-end close configuration, what chart of accounts and GL account master settings ensure tax-relevant accounts are correctly identified for statutory tax reporting?
