Batch processing matches input to output, and is therefore also a control over processing and output. Other examples of output controls include the controlled resubmission of rejected transactions, or the review of exception reports (eg the wages exception report showing employees being paid more than $1,000).
(iv) Master files and standing data controls
Examples include one-for-one checking of changes to master files, eg customer price changes are checked to an authorised list. A regular printout of master files such as the wages master file could be forwarded monthly to the personnel department to ensure employees listed have personnel records.
