How do I see who changed a work order and when?

How version history works

Once a work order reaches Assigned (or any later status), every update creates a read-only version snapshot — automatically, with nothing to configure. Work orders in Created or Ready do not create versions.

Each snapshot captures the complete previous state: status and priority, all expected and actual dates/times, performed-by and vendor selection, people and skill requirements, equipment and specialty materials, scope-of-work checklists, scheduler notes, custom field values, who made the change (user and email), and when.

View the version history

1. Open the work order's detail drawer.
2. Click Version History.
3. Browse the list of versions — each shows the version number, the date and time saved, the user who saved it, and the status at that version.
4. Click any version to compare it with the current or previous version.

Reading the comparison view

Differences are shown side-by-side (old value → new value) with changes highlighted, organized by section: Basic Information, Timeline (expected and actual), Resource Requirements, Equipment, Specialty Materials, Scope of Work, Scheduler Notes, and Custom Fields.

Rules to know

• Versions are numbered sequentially (1, 2, 3…) and are read-only — they cannot be edited or deleted.
• The first submission (Created → Ready) does not create a version.
• Version snapshots are created in the background and never block your save.
• Version emails depend on the work_order_modified_after_assigned notification event being enabled in notification settings; version snapshots and email delivery are independent of each other.
