Internal table with an internal table

Question

Hi,
I have following definition:
TYPES:  BEGIN OF ty_pos,
             numbertype(29)            TYPE c,
             number(29)                TYPE c,
             END OF ty_pos.
DATA: gt_pos TYPE STANDARD TABLE OF ty_pos,
      gs_pos LIKE LINE OF gt_pos.
TYPES: BEGIN OF ty_struc,
        city(29)                  TYPE c,
        country(29)               TYPE c,
        name(29)                  TYPE c,
        pos LIKE gt_pos,
END OF ty_struc.
DATA: gt_tab TYPE STANDARD TABLE OF ty_struc,
      gs_tab LIKE LINE OF gt_tab.
The problem is that the system don't know the fields when I say
  gs_tab-pos-number                = 'test'.
How should I write the syntax therefore?

Hi,
Check the code
TYPES : BEGIN OF t_gr,
          wrbtr TYPE ekbe-wrbtr,
          menge TYPE ekbe-menge,
          bwart TYPE ekbe-bwart,
         END OF t_gr.
  DATA :  i_gr    TYPE TABLE OF t_gr.
  TYPES : BEGIN OF t_ekbe,
           ebeln TYPE ekbe-ebeln,
           ebelp TYPE ekbe-ebelp,
           *llggr LIKE i_gr,*
          END OF t_ekbe.
   DATA : i_ekbe      TYPE TABLE OF t_ekbe.
   SELECT ebeln
          ebelp
          wrbtr
          FROM ekbe
          INTO TABLE i_ekbe1
          FOR ALL ENTRIES IN i_data1
          WHERE ebeln = i_data1-ebeln   AND
                ebelp = i_data1-ebelp   AND
                  bewtp = c_e          AND
                ( bwart = c_101        OR
                  bwart = c_102        OR
                  bwart = c_103        OR
                  bwart = c_104 ).
loop at i_ekbe1 into wa_ekbe1.
wa_ekbe = wa_ekbe1.
wa_gr-wrbtr = wa_ekbe-wrbtr
append wa_gr to i_gr.
on change of  wa_ekbe1-ebeln.
       INSERT LINES OF i_gr INTO wa_ekbe-llggr INDEX 1.
       APPEND wa_ekbe TO i_ekbe.
endon.
edloop.
the above code the ekbe table is having one move itab l_gr
l_gr is updated in each loop and and each change the i_ekbe is updated with one set of l_gr data as internal table line for i_ekbe.
Here u need to refer each table seperately.
parent table(EKKO) line has the child tables(EKPO).
