Answer 1

hello,
i doubt that there is such FM (i do not have table S700 in my system ECC 6.0 so i can not do any researches). If you want to get valuable answer post your select maybe we could help you to improve the speed of your code. Several advices which could help:
1) select only required fields do not use
select * statement
if it is not mandatory;
2)
do not use into corresponding fields of table
better use
into table
, but fields sequence in select and in yout internal table should be the same otherwise you will get dump during execution.
3) use primary key or index or define your new one (but defining new indexes willslow down insert update processes);
4) if you are using joins in you select try to split it into two sepatared ones (table types: hashed and standard).
data: lt_b type standard table of b,
        lt_a  type hashed table of a with unique key fieldname1 fieldname2,
        ls_b type b,
        lv_tabix type sytabix.
select A~fiendname1
          A~fiedname2
into table lt_A
from A
where (required clause).
select B~fieldname1
           b~fiedname2
          b~fieldname3
into table lt_B
from b
where (required clause).
loop at lt_b into ls_b.
  lv_tabix = sy-tabix.
  read table lt_a transporting no fields with table key fiedname1 = ls_b-fieldname1 fieldname2 = ls_b-fieldname2.
  check sy-subrc ne 0.
     delete table lt_b index lv_tabix.
endloop.
here you will find the main rules what is good and not (it could be valuable resource in your case):
