demoting UVM_ERROR

I'm trying to cancel an error,

in test.build_phase :

set_report_severity_id_action_hier(UVM_ERROR, "PKT_ERR", UVM_NO_ACTION);

but the error doesn't go away

EDIT:

problem solved: in test connect_phase if full hier given it works :

env.href.set_report_id_action_hier(UVM_ERROR, ""PKT_ERR", UVM_NO_ACTION);
