How to avoid dead lock error while updating ADRC table.

Hi,

There is one enhancement while changing vendor address which will update tables LFA1, ADR6 and ADRC.

While updating table ADRC, i'm receiving deadlock error.

DBIF_RSQL_SQL_ERROR - ORA-00060: deadlock detected while waiting for resource                

>>>>>              UPDATE adrc SET name1 = lv_name_first                                                  

                           name2 = lv_name_second                                                 

                           name3 = lv_name_third                                                  

                           mc_name1 = lv_fullname                                                 

                           flagcomm6 = lv_email_flg                                               

                           WHERE addrnumber = lv_adrnr.                                           

          IF sy-subrc = 0.                                                                       

            COMMIT WORK.                                                                         

          ENDIF.

Any suggestion, how can I avoid this error?

Thanks
