Permission: Variations Edit
The permission 'variations-edit', if present on your system will control which ProcessWire Admin users can edit variations configurations and attributes. A user without the permission will not be able to edit variations configurations or attributes.
Please note that if a user has editing rights but no lock or publish or delete permisions in cases where those permission are in effect, they will still not be able to implement any changes with respect to those actions whose permissions they lack.
Please note that this permission is not created when the module is installed. To use it, you will have to create it first then assign it to a role(s) which in turn are assigned to users, in the normal ProcessWire way.
