Select (join) into internal table with nested structures

Question

Hello Experts,
i wonder about the correct notation of a select statement.
I have an internal table it_zoll including  two structures as defined below.
The select is a join on the two tables zollp and zolls. As coded below the select is syntactically correct, but the fields
in the nested structures are not filled ....
Any ideas how to write the select statement ? (The internal table it_zoll must have the nested structures for other reasons ..)
Declaration:
TYPES: BEGIN OF ty_zollp,
  belnr     TYPE  zollp-belnr,
  werks     TYPE  zollp-werks,
  gebnr     TYPE  zollp-gebnr,
       END OF ty_zollp.
TYPES: BEGIN OF ty_zolls,
  grnum     type  zolls-grnum,
  werks     type  zolls-werks,
  name1     TYPE  zolls-name1,
       END OF ty_zolls.
DATA: BEGIN OF wa_zoll.
DATA: zollp type ty_zollp.
DATA: zolls type ty_zolls.
DATA: END OF wa_zoll.
DATA: it_zoll LIKE TABLE OF wa_zoll.
Select:
  SELECT
    zollp~belnr   zollp~werks  zollp~gebnr
    zolls~grnum zolls~werks  zolls~name1
      FROM zollp
      JOIN zolls ON   zolls~werks = zollp~werks
                 AND  zolls~grnum = zollp~grnum
      INTO CORRESPONDING FIELDS OF TABLE it_zoll
      WHERE zollp~werks = werks
      AND   zollp~gebnr IN s-gebnr
      AND ...
Thank you !

DATA: BEGIN OF ty_zollp,
  belnr     TYPE  zollp-belnr,
  werks     TYPE  zollp-werks,
  gebnr     TYPE  zollp-gebnr,
       END OF ty_zollp.
DATA: BEGIN OF ty_zolls,
  grnum     type  zolls-grnum,
  werks     type  zolls-werks,
  name1     TYPE  zolls-name1,
       END OF ty_zolls.
DATA: BEGIN OF wa_zoll.
Include structure ty_zollp.
Include structure ty_zolls.
DATA: END OF wa_zoll.
The above declaration had worked. Please try.
