In one of my queries, I implemented a time-dependant hierarchy. I have no trouble modifying the Key Date, but my key-users can't. I guess It's an authorization problem, but I can't find the right manipulation to do (new authorization role for user or RSSM manipulation).
A previous thread was on this subject:
But I don't know this apply to my case (since I can add a Key Date as a developer)
Thanks for your answers
