1. SAP S/4HANA 2023 Help Portal - Asset Accounting (FI-AA) - Chart of Depreciation:
"In a chart of depreciation
you define the depreciation areas that you need for valuation in your company. You assign an accounting principle to each depreciation area." This establishes the mandatory link between a depreciation area and an accounting principle
which is the foundation for the takeover logic.
2. SAP S/4HANA 2023 Help Portal - Asset Accounting (FI-AA) - Transfer of Values from Other Depreciation Areas:
"You can specify that a depreciation area takes over the acquisition and production costs (APC) and/or the depreciation terms from another depreciation area. The prerequisite for this is that the two depreciation areas belong to the same company code." While this source mentions the company code
the implicit and more fundamental prerequisite enforced by the system's architecture is the consistency of the accounting principle. The entire parallel valuation model in S/4HANA is built upon this principle-based separation.

Path: Financial Accounting -> Asset Accounting -> General Valuation -> Depreciation Areas -> Define Depreciation Areas. The configuration and associated help text for this node detail that each area's valuation is dictated by its assigned accounting principle. The system logic for value takeover (in Specify Transfer of APC Values) enforces this consistency
preventing a takeover between areas with conflicting accounting principles.
