Declaring variable dynamically

Former Member — Mon, 31 Mar 2008 12:47:14 GMT

Hi all,

I want to accept a table name, and declare an internal table which is of type of that accepted table.

Use type any.Type any is used when the type is unknown.

Use field symbols

field-symbols: <fs1>

you can assign any type to field symbol at run time

Dont forget it should be a field symbol or it is not possible.

Example field symbols test type any.

Then u can assign it to any thing.

you can use the below syntax.

field-symbols: <fs> type any.

data: var(9).

var = 'IT_VBAP[]'.

assign (var) to <fs>.

There are many ways to do this. Above is one such.

You can use

Field-symbols: <fs_tab> type any table.

This filed symbol then can accept any table dynamically.

you can process this dynamically filled table by statement

Loop at <fs_tab> into <wa_tab>.

loop at <wa_tab> assigning componets of <wa_tab> to <field>

endloop.

This way you process any table dynamically.

Reward points if helpful

field symbol should be assigned to an internal table here, how do i declare that internal table whose type is unknown

Re: Declaring variable dynamically

Former Member — Mon, 31 Mar 2008 13:01:55 GMT

You can also do this...

data: tab type ref to data.

DATA: it_vabp TYPE STANDARD TABLE OF vbap WITH HEADER LINE.

select * from vbap into table it_vabp .

GET REFERENCE OF it_vabp[] INTO tab.

field symbol should be assigned to an internal table here, how do i declare that internal table whose type can not determined statically? the user will enter the type

I want to know how to fill the internal table dynamically?

You can do that using the method of class

cl_alv_table_create method is create_dynamic_table

REPORT  Z_TEST_09.

DATA:
  i_newtable  TYPE REF TO data.        " To create dyn.Itab
  DATA: w_tabname TYPE w_tabname,
        w_dref TYPE REF TO data,
        w_grid TYPE REF TO cl_gui_alv_grid.

  FIELD-SYMBOLS: <t_itab> TYPE ANY TABLE.

  w_tabname = p_table.

CALL METHOD cl_alv_table_create=>create_dynamic_table
    EXPORTING
      i_style_table = 'SPFLI'
    IMPORTING
      ep_table        = i_newtable.

 ASSIGN i_newtable->* TO <t_itab>.
  SELECT *
    FROM (w_tabname) UP TO 20 ROWS
    INTO TABLE <t_itab>.

CREATE OBJECT w_grid
    EXPORTING i_parent = cl_gui_container=>screen0.

  CALL METHOD w_grid->set_table_for_first_display

      it_outtab        = <t_itab>.

Hi Yash,

its giving syntax error, can u please have a look at it?
