Hi,


assign (p_tc_name) to <tc>.


TYPES:
  BEGIN OF st_mytable,
    name1 TYPE string,
    name2 TYPE string,
    age TYPE i,
  END OF st_mytable.

DATA:
  gi_mytable TYPE STANDARD TABLE OF st_mytable,
  g_mytable  TYPE st_mytable.

*------------------------------
* Define field symbols
*------------------------------
FIELD-SYMBOLS:
  <myfield1> TYPE ANY,
  <myfield2> TYPE ANY,
  <myfield3> TYPE ANY,
  <myline>  TYPE ANY.

*------------------------------
* Fill table with data
*------------------------------
g_mytable-name1 = 'John'.
g_mytable-name2 = 'Johnson'.
g_mytable-age   = 25.
APPEND g_mytable TO gi_mytable.

g_mytable-name1 = 'Claudio'.
g_mytable-name2 = 'Jensen'.
g_mytable-age   =  45.
APPEND g_mytable TO gi_mytable.

*------------------------------
* The normal way to do it
*------------------------------

LOOP AT gi_mytable INTO g_mytable.
  WRITE: / g_mytable-name1, g_mytable-name2 ,g_mytable-age.
ENDLOOP.

SKIP 2.

*------------------------------
* Do it with field symbols
*------------------------------
LOOP AT gi_mytable ASSIGNING <myline>.
  ASSIGN COMPONENT 1 OF STRUCTURE <myline> TO <myfield1>.
  ASSIGN COMPONENT 2 OF STRUCTURE <myline> TO <myfield2>.
  ASSIGN component 3 OF STRUCTURE <myline> TO <myfield3>.
  WRITE: / <myfield1>,<myfield2>,<myfield3>.
ENDLOOP.

*------------------------------
* Unassign field symbols
*------------------------------
UNASSIGN <myfield1>.
UNASSIGN <myfield2>.
UNASSIGN <myfield3>.
UNASSIGN <myline>.

hi guru,

g_mytable- name1 = 'John'.

g_mytable -name2 = 'Johnson'.

g_mytable- age = 25.

I should assign the the Field name directlly(Name1,Name2.Age).

see the example...


*   Moving Batch Characteristic values to proper fields
  LOOP AT t_zcxref_classes INTO wa_zcxref_classes.
    IF wa_zcxref_classes-z7b1_main_column IS NOT INITIAL.
      CONCATENATE 'wa_7b1_in-'  wa_zcxref_classes-z7b1_main_column
             INTO w_char_name.
      CONDENSE w_char_name.
      ASSIGN (w_char_name) TO <fs_char_name>.
      IF sy-subrc = 0.
        <fs_char_name> = wa_zcxref_classes-atwrt.
*         Updating  Batch Characteristic values
        MODIFY t_7b1_in FROM wa_7b1_in INDEX 1
                 TRANSPORTING (wa_zcxref_classes-z7b1_main_column).
      ENDIF.
    ENDIF.
    CLEAR w_char_name.
  ENDLOOP.

for your cobe..


concatenate 'wa_SFLIGHT-'  <lv_field>  into w_char_name.
ASSIGN (w_char_name) TO <lv_field>.

The way you are creating is wrong. Please follow the steps below.

1. Create a field catalogue with the fields (dynamic).

2. Pass it to the below class

IF NOT i_fldcat[] IS INITIAL.

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = i_fldcat[]

IMPORTING

ep_table = i_table

EXCEPTIONS

generate_subpool_dir_full = 1

OTHERS = 2

IF sy-subrc <> 0.

ENDIF. " IF sy-subrc <> 0.

3. Assign the table to one dynamic table and work area.

ASSIGN i_table->* TO <i_output>.

CREATE DATA fs_line LIKE LINE OF <i_output>.

ASSIGN fs_line->* TO <fs_output>.

ENDIF. " IF NOT i_fldcat[] IS INITIAL.

So that you can achieve your job.
