Hello !
Thks for your quick reply,
I'm from France sorry for my bed english but i hope u're understanding me, I'm new consultant in BW and like u know woman are not very comfartable with IT 
so i'm going to ask u 2 others questions about hierarchy and saving query in roles if u don't mind 
1) I want to change some hierarchy node position in production system, do i change directly in rsh1 by adding a node to another level ? or i must to change in a file source or ECC system ? if i change just on rsh1, i will lost all i have changed when Info package will be executed (in daily process chain)...? that's right?
2) I have a query already published in rôle, but i have to move it to another one, how can i do that in query designer please?
PS : i can't send you direct message, is it possible to follow me ?
Thks in advance have a nice day !
