Opening the most recently used object

You can click the MRU (most recently used) button to open any of the last few top-level structures you opened. This list is saved across sessions and is an easy way to reopen structures you were previously working on. Click an item revision in the MRU list to open it.

Note

If the business object display rule for the Item business object is hidden in the Business Modeler IDE, Service Plan does not show up in the most recently used (MRU) list.
