Hi Shiva,
I am using two more select queries with the same manner ....
here are the other two select query :
***************1************************
SELECT * APPENDING CORRESPONDING FIELDS OF TABLE tbl_summary
    FROM ztftelpt LEFT JOIN ztfzberep
     ON  ztfzberep~gjahr = st_input-gjahr
     AND ztfzberep~poper = st_input-poper
     AND ztfzberepcntr  = ztftelptrprctr
    WHERE rldnr  = c_telstra_projects
      AND rrcty  = c_actual
      AND rvers  = c_ver_001
      AND rbukrs = st_input-bukrs
      AND racct  = st_input-saknr
      AND ryear  = st_input-gjahr
      and rzzlstar in r_lstar             
      AND rpmax  = c_max_period.
and the second one is
*************************2************************
  SELECT * APPENDING CORRESPONDING FIELDS OF TABLE tbl_summary
    FROM ztftelnt LEFT JOIN ztfzberep
     ON  ztfzberep~gjahr = st_input-gjahr
     AND ztfzberep~poper = st_input-poper
     AND ztfzberepcntr  = ztftelntrprctr
    WHERE rldnr  = c_telstra_networks
      AND rrcty  = c_actual
      AND rvers  = c_ver_001
      AND rbukrs = st_input-bukrs
      AND racct  = st_input-saknr
      AND ryear  = st_input-gjahr
      and rzzlstar in r_lstar                              
      AND rpmax  = c_max_period.
for both the above table program is taking very less time .... although both the table used in above queries have similar amount of data. And i can not remove the APPENDING CORRESPONDING. because i have to append the data after fetching from the tables.  if i will not use it will delete all the data fetched earlier.
Thanks on advanced......
