SAP XI: Recovering Deleted XI Objects
This has happened to us when one of the developer's deleted other's XI objects by mistake. This trick was helpful in saving a lot of rework/restore time. If you delete any XI object by mistake, you can recover them by creating a dummy object with the same name and activating the original one from history. This method may not work on a few objects. If you choose to export the object from another system (ex: from QA to Dev) in the landscape, make a note of Namespaces in SWCV. During import, the SWCV also gets updated and it might cause the newly added Namespaces (Dev system's SWCV may have more Namespaces in its list) and their objects to disappear (not deleted)
