Overview

The Change Log provides a complete audit-friendly history of actions and status changes for a Basic UDI-DI or Device in UDI Hub. It helps you answer:
  • Who performed an action (user or system)
  • What happened (Upload / Import / Submit, approvals, validations, status changes)
  • When it happened (timestamp)
  • Whether validation was successful or not successful
  • How the history differs between versions (e.g., initial registration vs. updates)

​
Where to find it

  1. Open UDI Management
  2. Open the Details modal of a Basic UDI-DI or Device
  3. Go to the Change Log tab

​
Version-specific view vs. complete history

In the Change Log you can switch between:
  • Current Version (vX) — shows changes related to the currently selected version
  • Complete History — shows the full history across all versions
This is useful to distinguish what happened during:
  • Version 1 (initial registration), versus
  • later versions (updates / follow-ups)

​
What you will see in the log

Each log entry typically includes:
  • an event title (e.g., New Import for Device, Submission triggered, Approval for Device)
  • the actor
    • a user (when triggered manually, e.g., import or submission)
    • System (when statuses are set automatically in the background)
  • a timestamp
  • optional details you can expand via Show details
The Change Log includes, among others, these types of events:
  • Upload: file upload activity that leads into validation
  • Import: import actions
  • Submit: a submission being triggered for a Basic UDI-DI or Device
  • Validation: e.g., Validation Successful or validation failures
  • System status updates: e.g., approvals set after successful import

Export an Audit Trail (PDF)

For audits and internal documentation, you can export the audit trail as a PDF:
  1. Open the Change Log tab
  2. Click Download Audit Trail
  3. Choose the required export option (e.g., for the current version or complete history, depending on your configuration)
This export provides a shareable audit document containing the recorded history.

Tip

Use Current Version when you want to explain or troubleshoot a single submission/update cycle.
Use Complete History to provide a full audit trail across initial registration and all updates.
