Hi
U can leave ORDER BY option and sort the table by yourself and try to split the query:
SELECT * FROM zv7_custord
     INTO TABLE G_T_ZV7_CUSTORD
     WHERE  SENDER in S_SENDER and
                   ORDNUM in S_ORDER  and
                   ZDATE   in S_DATE .
SELECT * FROM zv7_custord
     APPENDING TABLE G_T_ZV7_CUSTORD
     WHERE  SENDER in S_SENDER        and
                   NOT ORDNUM in S_ORDER  and
                   NOT ZDATE   in S_DATE       and
                   STATUS = SPACE
or
SELECT * FROM zv7_custord
     INTO TABLE G_T_ZV7_CUSTORD
     WHERE  SENDER in S_SENDER and
                   ORDNUM in S_ORDER  and
                   ZDATE   in S_DATE .
SELECT * FROM zv7_custord
     APPENDING TABLE G_T_ZV7_CUSTORD
     WHERE  SENDER in S_SENDER        and
                   STATUS = SPACE.
* Sort the table key fields
SORT G_T_ZV7_CUSTORD BY <KEY1> <KEY2> .....
DELETE ADJACENT DUPLICATES FROM G_T_ZV7_CUSTORD COMPARING <KEY1> .....
