What is a tracked field?

A tracked field is a field the system is monitoring. When a field is tracked the system will create a log file that records when, what, and who made changes to the field content. Some fields contain sensitive information that may change the way a routine calculates or a report runs. For example, you may want to track changes to the customer's account number, social security number, or birth date.

You have three options that can be used separately or all together:

You can use History Tracking to set up the application to record any changes to the information in the selected field. When you use this option, click the History (CTRL+H) button to show the tracking log.
You can use Management Tracking when you want to include any changes to the tracked field on the management report, but not include it on any other report that displays changes to fields selected for History Tracking. Use Reports > Management Report to print the Management Tracking report.
You can Management Deletions to record when information in a field is deleted and the field is left blank. Use Reports > Management Report to print a list of fields with values that have been deleted.
