if($data['action'] == 'EDIT'){
            $this->db->where('mspr_no', $data['ms']['mspr_no']);
            $this->db->update('ms_promo', $data['ms']);

            $this->db->where(array('mdpr_no' => $data['md']['mdpr_no']));
            $this->db->delete('md_promo');

            if(!empty($data['md'])){                
                foreach ($data['md'] as $key => $value) {                   
                    $this->db->update('md_promo', $value);
                }
            }
