As of Release 4.0 

As of Release 4.0, you can set the following change options using transaction SE06:

·        Repository and Client-Independent Customizing not modifiable

With this setting, you cannot change any objects. We recommend this setting for productive systems.

·        Repository and Client-Independent Customizing modifiable

With this setting, you can change objects according to the specific settings for each namespace.

For modifiable systems, you have to define to what extent you can make changes for each namespace. You can:

·        Allow changes to all objects  (Choose Edit à Select all.)

With this setting, you can modify or repair objects from the SAP standard. This also includes the full scope of changes to customer objects.

·        Allow changes to your own objects only (Choose Edit à Select all own.)

With this setting, you can modify all of your own objects. (Own objects are objects belonging to namespaces with a producer role. If you use this setting, then these namespaces are marked as changeable.)

·        Assign changes for each namespace individually.

With this setting, you can change all objects belonging to namespaces that are set to changeable.
