Testing File Update Controls. Failure of file update controls to function properly
can result in transactions (1) not being processed (liabilities are not recognized and recorded),
(2) being processed incorrectly (i.e., payments are approved for unauthorized
recipients), or (3) being posted to the wrong supplier’s account. Tests of file update controls
provide the auditor with evidence relating to the management assertions of existence,
completeness, rights and obligations, and accuracy.
