It's simple. Assign shadow catcher material to plane that receive shadow, set alpha mode to "for compositing", assign ray switcher material to object that should cast shadow, unplug material from all slots but global illumination and you're good to go.

Thank you very much. Just the confusing part for me is : "unplug material from all slots but global illumination"

Actually I'm worse at understanding :D
Thats why, then I realized only upon opening the scene attached, very kind of yours to create the scene..

Thank you again!
