Which master records are directly assigned to a company code?

In SAP, the master records that are directly assigned to a company code include Fixed Assets (D) and Activity Types (C). Fixed Assets are managed within the company code for asset accounting purposes, and Activity Types, used in Cost Center Accounting, can also be company code-specific, especially when used for internal cost allocations and calculations.References= SAP Financial Accounting (FI) and Controlling (CO) documentation and master data setup guides.
