If the selected project was inherited from an existing project template, there will be an additional tab named 'Inheritance Option' while editing the project. Only users with admin access to the project template can update the configuration of projects cloned from that project template without breaking the inheritance between the project template and the cloned project.
In case you have multiple projects cloned from a project template, and when you need to change project configuration on some of those projects, it is advisable to follow the following guidelines:
Suppose a change in folder configuration is specifically required on a project. In that case, you can create a new folder with the configuration needed for that project.
Suppose a similar configuration is required for the other projects. In that case, it is best to communicate the general configuration to the relevant project manager and update it directly on related project templates so that all projects can benefit from it.
Under the 'Inheritance Option' tab, a list of workspace objects appears. The details of selected workspace objects are copied from the related project template to the cloned project which is being edited.
A tick appears under the 'Inherit Changes' column if the changes to the corresponding workspace object are inherited from the related project template from which the selected project was cloned (as shown in the screenshot below).
If the 'Inherit Changes' checkbox for an object is showing ticked and disabled, it means that a particular object has some relation with other objects in the list. Click here to understand the relation between workspace objects.
If needed, you can also break the inheritance of related objects in the project that is being edited.
