A quantity changes from ten to six, and the team cannot tell whether it was a correction, a return or an import. A useful history gives enough context to understand the event.
Choose the meaningful events
Identify important field changes, approvals, status transitions and external actions. Record the actor, time, affected record and relevant before-and-after values where appropriate. Keep the purpose and privacy of the history in mind.
A technical log and a business history serve different readers. Staff may need a readable explanation and source reference, while a maintainer needs a controlled diagnostic trace.
Decide how corrections appear
An authorized correction should not erase the fact that a previous value existed if the business needs that history. Record the reason and preserve related references under the agreed policy.
Test a manual edit, an automated update and a rejected action. Ask an ordinary user to explain the history without reading code.
The project scope should name which events are retained, who can view them and how long they are needed. That creates a practical investigation tool rather than an uncontrolled second store of private information.
Show time zones consistently in the history. A timestamp that means different things to office and field users can make an otherwise accurate sequence difficult to interpret.
