NetSuite employs System Notes to meticulously document any modifications made to a record. These notes capture crucial information such as the date and time of the change, the initiator of the change, the interface used, the type of change, the specific field that underwent modification, and the before-and-after values within the record. Notably, System Notes maintain an unalterable status, impervious to edits by system users, scripts, or applications. This indelible nature extends to both custom and standard records, ensuring a secure and unmodifiable record-keeping system.
