Planon enables you to keep track of changes made to fields by enabling the History functionality. This includes the user who changed the value in a field, the old and new values of the field and the time and date at which the value was changed. Your application manager can enable an automatic History option for individual fields in Field definer. For more information, see Configuring the history feature.

With the appropriate authorization, you can also manually add a history of changes to the selected field, via the action panel. Any comments you want to make on changed data can be specified in the Comment field and subsequently saved. To enable history manually, see Adding history manually.

Following GDPR legislation, any personal data stored even in history records must be anonymized. To anonymize history in Planon , see Anonymizing history.
