Made a change you'd rather undo? Your semantic layer keeps its earlier versions, and you can bring one back — all of it, or just the parts you want.
Before you start: open the semantic layer and check its publishing mode. Restoring changes the shared draft, so other authorized editors can see the restored state. Delayed or Instant mode can publish it automatically once the publishing checks pass.
Find the version you want
Step 1: Click Versions in the toolbar.
The Version history panel opens on the right.
Step 2: Look through the list. Versions are grouped by day, newest first, and each one shows the time it was taken, its revision number, and who made the change.
The one you're working on is badged Current Version. The oldest is Initial version — the layer as it was when you started.
Tip: a version showing No contributor is one the editor took by itself rather than one a person saved.
Check what changed between versions
Rather than restoring blind, look first.
Click the ⋮ menu on the version you're interested in.
Choose Compare. (An earlier version also offers Rename version, Remove version and Restore version.)
Result: the two versions open side by side — the older one marked Compared Version, yours marked Current Version — with a count of what's different between them.
Changes are grouped by entity type. Each entry names what changed and how many properties were affected.
Bring back an earlier version
From the comparison you have two choices.
Take everything. Click Restore all from Rev 0 — the button names the revision you're restoring from, and shows how many changes that involves.
Take only some of it. Tick the individual changes you want and restore just those, leaving everything else as it is. Useful when one measure went wrong and the rest of your work since is worth keeping.
You can also skip the comparison entirely: open the ⋮ menu on a version and choose Restore version.
Restore all and Restore selected in the comparison apply changes to the draft immediately, without a separate confirmation. Restore version from the version menu opens Restore this version? and waits for you to confirm.
Result: restoring a whole version replaces the shared draft with that version. Restoring selected changes updates only those parts. The saved change creates a new revision; it does not erase the intervening history.
Publication follows your selected mode. In Manual mode, the restored draft waits for a publish. Delayed and Instant modes can publish it automatically. For publishing modes and checks, see Publish your changes.
Name a version so you can find it later
Timestamps are hard to tell apart a week later. Give the important ones a name.
Click the ⋮ menu on a version.
Choose Name version.
You can name the version you're working on too. It's already named, the menu says Rename version instead — and alongside it Remove version, which takes that restore point out of your history without changing your model.
Tip: name a version before you start something risky — restructuring joins, renaming measures, a big tidy-up. It takes a second, and it turns "I think I can get that back" into "I know exactly which one to go back to".
Next: Continue to Publish your changes.
