Re: How to recover the deleted business needs (tactics) from the application
If the transaction (or private workspace) has yet to be dispatched, the undo functionality can be used.
However, if the shared repository has been publicly updated thisis not as simple. I propose restoring a copy of a backup (save) of the environment in order to retrieve the desired contents. Be careful not to squeeze/crush the production data with this backup data but to restore it beside the current data. The environment can be referenced via MEGA Administration as long as it has a different name than the production environnment. You then open the repository, export via MGR the objets and diagrams you seek, then import this file into the production environment. Standard export propagation may take more or less than you desire so be aware of links and addtional objects.
