When you are customizing an existing view and want your customized view to replace the existing view across the application, you can do so without modifying the links, actions, and icons that point to the existing view.
The existing links, actions, and icons point to a view group ID. However, they do not point to a specific view when a screen is navigated to using these links, actions and icons. The screen is opened as the view that has the lowest sequence number of all views with that view group ID.
Therefore, to replace an existing view across the application, ensure that your customized view has the same group ID as the original view and has a sequence number lower than the original view sequence number.
For example, if you are replacing the standard order detail view with a customized view, the customized view must have a view group ID of YOMD010.
If your custom view is an additional screen that is not replacing an existing view, you must add your own links, actions, or icons in the appropriate places such that it can be used to navigate to your screen.
Your view should have a unique view group ID. The links, actions, or icons you create should point to this view group ID.
