Running a Business Rule from an Scheduled job

Hello everyone.

I have a Business Rule, and I want to run it periodically, to validate an expiration date on a record, the BR works properly, but because of the nature of BRs I have to either update or insert the form, for it to trigger, I read that we could run it from an scheduled job, but I haven't found the way to set the relation between them.

var now = gs.endOfYesterday();

var vigencia = current.u_fecha_fin; //expiration dateif(vigencia < now){

current.u_hrs_vencidas = current.u_hrs_restantes;

current.u_hrs_restantes = 0;

current.u_activo = 'true';

gs.addInfoMessage("TEST");

}

Could anyone please help me find the best way to do this?

Thanks in advance and regards!.
