An auditor is evaluating the 'Completeness' of data transfer from a legacy system to a new ERP. Which technique is MOST effective?

Answer options:

Record counts and Hash totals

Limit checks

Check digits

Validity checks

How to approach this question

Completeness = Did we lose anything? Count them.

Full Answer

A.Record counts and Hash totals✓ Correct

Record counts (counting the number of rows) and Hash totals (summing a non-financial field like Customer ID) are primary controls to ensure that the exact volume of data sent was received, verifying completeness.

Common mistakes

Selecting input validation controls (Limit/Check digit) instead of batch controls.
