Which of the following are components of an account group in financial accounting?

In financial accounting within SAP, account groups are essential for categorizing and managing different accounts. The components of an account group mainly include the different types of accounts that can be configured under that group, along with their associated attributes. General ledger account numbers are directly related to these components, as they define the specific accounts that belong to the group. Each account group specifies characteristics such as number ranges, account types, and parameters unique to the accounts within that group, making the general ledger account numbers a foundational aspect of how account groups function.

Other options may relate to financial processes but do not form a core part of the structure of an account group. Cost center assignments are related to controlling and overhead management rather than the direct categorization of financial accounts. Transaction codes are functionalities used to execute various processes in SAP, without being a component of account groups. Vendor classifications pertain to the categorization of suppliers, which is separate from the financial account classification system defined by account groups.
