S4和ECC或者不通CLIENT，不通HANA服务器互相取数
1.DBCO(如下链接服务器信息由BASIS提供)
2.通过SELECT读取
SELECT *
FROM (ls_ztbc007_pz-tabname)
" CLIENT SPECIFIED BYPASSING BUFFER CONNECTION (gv_con_name) "gv_con_name = SAP-ECC-230 跨CLIENT
" BYPASSING BUFFER CONNECTION (gv_con_name)"gv_con_name = SAP-ECC-230 不跨CLIENT
INTO TABLE <gt_table_content> "PACKAGE SIZE p_size
FOR ALL ENTRIES IN lt_ztbc007
WHERE knumh = lt_ztbc007-knumh.
