Hash Total

Sum of a non-financial field, such as account numbers, used solely as a batch control.

Definition

A hash total has no business meaning but changes if records are added, removed, or altered. It is compared before and after processing to verify integrity of a batch. It is distinct from a cryptographic hash.

Example

Adding all vendor numbers in a batch yields a hash total of 4,872,301 to verify completeness.

Exam tip

Don't confuse a hash total (batch control) with a cryptographic hash function.
