When doing Items ribbon configuration, you may want to include a button for a configured item view on the ribbon. In order to do this, you would neither either the xID or the Ref id for the config item you plan to include. This article describes how to search for and find the xID for a Config Item (C).
Run a search for the configured views using Open item>Other item type.. and selecting the config item type of the definition you are searching for. In the below example, the search is for configured graph definitions.
Then, retrieve the xID for the config item by either opening it and copying the xID from the Properties view or copying (Ctrl+C) the item itself in the tree and pasting it in to a text editor.
Once you have retrieved all of the XIDs, you are ready to configure button options on the Items ribbon.
