The use of control totals reduces the risk of:

Posting to the wrong record is typically addressed by validation controls that check account numbers or identifiers, not primarily by control totals for overall batch completeness.

Improper backup relates to data retention and recovery procedures, which are separate from processing controls like control totals.

Improper authorization is mitigated by access controls and approval workflows, not by control totals which verify data completeness during processing.

Control totals, such as record counts or hash totals, are used to reconcile the number of items or specific values entered into a system against those processed. By comparing the totals before and after processing, organizations can detect if any records were dropped or incompletely processed, ensuring data integrity and completeness.
