SELECT - JOIN 
Syntax 
... [(] {data_source [AS tabalias]}|join 
          {[INNER] JOIN}|{LEFT|RIGHT [OUTER] JOIN} 
             {data_source [AS tabalias]}|join ON join_cond [)] ...  . 
Addition: 
... ON join_cond 
Effect 
Joins the columns of two or more database tables in a results set in a join expression. A join expression links a left side to a right side, using either [INNER] JOIN or LEFT|RIGHT [OUTER] JOIN. A join expression can be an inner join (INNER) or an outer join (LEFT OUTER) or RIGHT OUTER) join. Every join expression must contain a join condition join_cond after ON (see below). The following applies to entries specified on the left side and on the right side: 

  SELECT A~PROCESS_TYPE
         A~STAT_USER
         C~P_DESCRIPTION
         sum( ZAF_PRICE ) as ZAF_PRICE
    INTO CORRESPONDING FIELDS OF TABLE GT_ORDER
    FROM ZHSB_ORDER_INDEX AS A
    INNER JOIN CRMD_ORDERADM_H AS B
    ON A~GUID = B~GUID
    LEFT JOIN CRMC_PROC_TYPE_T AS C
    ON A~PROCESS_TYPE = C~PROCESS_TYPE
    WHERE (GT_WHERE)
    AND A~SALES_ORG IN S_ORG
    AND A~PROCESS_TYPE = P_TYPE
    AND B~CHANGED_AT BETWEEN GV_FROM AND GV_TO
    GROUP BY a~PROCESS_TYPE a~STAT_USER C~P_DESCRIPTION.

    SELECT * INTO CORRESPONDING FIELDS OF TABLE gt_order
      FROM CRMC_PROC_TYPE_T
      FOR ALL ENTRIES IN gt_order
      WHERE PROCESS_TYPE = gt_order-PROCESS_TYPE.
