As project teams grow larger and models scale in size and complexity, it becomes more and more difficult to stay abreast of the latest changes. Processes, baselining, and other techniques help manage and control the design evolution. Basic alerts and the Notification Center item in the Utilities section of the project explorer complement those processes helping to highlight the information that is most critical to you.
Borrowing a page from social media, CORE allows you to follow the objects of greatest interest. You can follow a specific element (perhaps a change request package working its way through the review process), a package (maybe your subsystem), or a folder (such as all interfaces). Once you set up to follow an object using the Follow command on the Manage submenu, CORE proactively notifies you of all changes made by other system users. This includes attribute changes, new relationships, moving an element to a new folder, even changing permissions. If it changes, you will know it.

The Notification Center does not track your changes to objects in which you have registered an interest. It only reflects those changes made to these objects by other users. |
The Notification Center in the Project Explorer is where you will go to see what changes have occurred, who made them, and when. You can open views directly from the Notification Center, assess the impact, and clear the alert when you have finished your review. As you collaborate with your team – particularly as you collaborate live using CORE Server – the Notification Center becomes exceptionally valuable as it helps you highlight the information most crucial to you. In fact, it’s so valuable that you can make this your project home screen by setting it in your User Preferences.
The notifications pane lists all alerts for changes to objects that you have chosen to follow. These notifications will remain until you clear them or until the project is exported and imported (they are not considered part of the project data but instead are a complementary capability).
For each notification, you will see:
The timestamp when the change was made
The user account that made the change
The class of the element changed
The name of the element changed
A brief description of the change.

Tips and Tricks Leverage the power of the table view to organize the changes to fit the way you work. By default, notifications are listed from newest to oldest. Drag the column headers to reorder the columns. Double-click a column header to sort by that column (to see all of the changes to a given element or all of the changes made by a specific user). |
The list box displays all of the objects currently being followed.
Folders are prefaced with the label "Folder." When you follow a folder, you receive notifications for any changes to elements in that folder or any subfolder.
Packages are prefaced with the label "Package." When you follow a package, you receive notifications for any changes to elements in that package or any sub-package.
Elements are prefaced with the class name.
Data menu
Open Element view submenu (to open any appropriate view for the element associated with the selected notification)
Utilities menu
Delete
Pop-up (right-click on the notification in the Notifications list)
Open Element view submenu
Pop-up (right-click on the object in the Current Following list)
You can open a property sheet for the changed element directly from the notifications list by double-clicking the notification.
You can quickly sort by a given column by double-clicking in the column header. Double-clicking a second time will change the direction of the sort (the arrow in the header indicates the columns used for sorting and the current direction).
Be strategic and deliberate about what you choose to follow and when you follow it. For example, following too many objects may cause you to overlook or ignore changes to critical objects of interest. Similarly, following objects early in their lifecycle may overload you with notifications. Conversely, if you truly are interested in any change to a package or a folder, register your interest at that level to simplify notification management and ensure you receive the notifications you need.
In general, the fastest way to stop following an object is to leverage the Current Following list in the Notification Center. This avoids having to navigate through the model to access a folder, package, or element.
