On Harvest 7.1 we could create a path on a repository and this path was visible in all views on the Harvest project.
How to create an Item path directly in the repository on version 12.5 and 12.6?
In harvest 5.x and 7.x, the path is NOT versioned, and path is global. That is why you can update the baseline of a project when a repository is updated.
Starting in Harvest R12.x with refactoring change, the item path is now versioned. So once a repository is baselined, all the paths are versioned, you can not use admin to add or remove paths anymore.
To add a new path after the project has been baselined you will need to use the Create Path process.
