Set current root, hide roots in RH_TYPE_STRUC_HELP
I am using RH_TYPE_STRUC_HELP to select the list of org.units. Also I have an option in my report: "head org.unit". I would like to hide all other roots except "head org.unit" and also be able to start the org.tree from "head org.unit".
restrict_callback - can only disable but cant hide.
Maybe I have to use other FM? Any examples?
