FOR ALL ENTRIES IN Problem

Question

Hello,
probably it is a silly problem, but can anybody tell me why this FOR ALL ENTRIES IN statement does not fill all the columns of my internal table?
At the end of the report only the columns LGOBE contains values.
data itab type zmm_t_alv.
select mardmatnr mardwerks mardlgort mardlabst
  maktspras maktmaktx
  into corresponding fields of table itab
  from mard inner join makt
    on mardmatnr = maktmatnr
where makt~spras = 'D'.
select lgobe
  into corresponding fields of table itab
  from t001l
  for all entries in itab
  where t001l~werks = itab-werks.
break-point.
Thanks,
Manuel

Please read the documentation aboutr for all entries
For all entries selects all records from a db table which correspond to the entries in an internal table, the result must be stored in a different table.
Otherwise use a loop at itab.
   select single ...
   modify itab
   endloop
Be careful with empty For all entries tables, it behave like a ranges table, no entry means no restriction and you get all records from the db table. That is a different behavior than the loop above.
Use   field1 field2 ... in corresponding fields of ....
If you specify only one field then you get only one result.
If you want one the field 'lgobe' then use into wa-lgobe and not the much slower into corresponding!
