The greatest concern for an IS auditor if there are flaws in the mapping of accounts between a front-end subledger and a main ledger is the inaccuracy of financial reporting. A subledger is a detailed record of transactions for a specific account, such as accounts receivable, accounts payable, inventory, or fixed assets.
A main ledger is a summary record of all transactions for all accounts in an accounting system. The mapping of accounts between a subledger and a main ledger is the process of linking or reconciling the transactions in the subledger with the corresponding entries in the main ledger. If there are flaws in the mapping of accounts, such as missing, duplicated, or incorrect transactions, the main ledger may not reflect the true financial position and performance of the organization. This may lead to inaccurate financial reporting, which may affect decision making, compliance, auditing, taxation, and stakeholder confidence.
Double-posting of a single journal entry, inability to support new business transactions, and unauthorized alteration of account attributes are not the greatest concerns for an IS auditor if there are flaws in the mapping of accounts between a front-end subledger and a main ledger. These are possible consequences or causes of flaws in the mapping of accounts, but they do not have as significant an impact as inaccuracy of financial reporting. Double-posting of a single journal entry may result in errors or discrepancies in the main ledger balances. Inability to support new business transactions may indicate limitations or inefficiencies in the accounting system design or configuration. Unauthorized alteration of account attributes may suggest weaknesses or breaches in access control or segregation of duties.
