You do not need any tables statement. Just leave it away

personally I do not like the declaration of table with
header lines and occurs and I did not figure out what you want to do with the count column in your internal table

There are tons of threads here advising not to use nested selects - in this case you could read the name of lfa1 right before you write it.
select aebeln alifnr abedat sum( bnetwr )
     into table itab
from ekko as a inner join ekpo as b
              on bebeln =   aebeln
where abedat in s_bedat group by aebeln
ebeln alifnr abedat.
should work
(corresponding is not necessary but would not work, unless you do not use " sum( b~netwr ) as netwr ".
make sure to sort the table before loop over it

here you could read your name if you must.
select single name1 from lfa1 into itab-name1
        where lifnr = itab-lifnr.
