You want to assign your 3 newly created company codes to the same controlling area.

When assigning newly created company codes to the same controlling area in SAP S/4HANA, it is essential to ensure that certain settings are consistent across all company codes. The required common settings include:

Fiscal year variant: The fiscal year variant defines the financial periods and special periods used for accounting. Having a common fiscal year variant ensures that all company codes within the same controlling area follow the same financial period structure, facilitating consolidated financial reporting and management.

Operating chart of accounts: The operating chart of accounts is the primary list of accounts used for financial accounting. It must be uniform across all company codes in the same controlling area to ensure consistent financial data recording and reporting, enabling accurate internal and external financial analysis.

These settings ensure that financial data is harmonized across the company codes, supporting integrated financial management and reporting.
