When you create a derived attribute, feature or report section in the Config project, then the corresponding Config attribute in your online projects will be created as soon as the next case is processed by the system. It will have the same name as the corresponding item in the Config project, and will appear by default as the last attribute of the case view, as shown below:
Once created, you can rename a Config attribute in the online project. The value for this attribute will still be generated by the corresponding item in the Config project, even though its name in both projects will now be different. Similarly, you can reorder a Config attribute in the online project, or place it into a folder.
Conversely, you can safely rename an attribute, feature or report section in the Config project. It will still correspond to its Config attribute in the online projects.
