Create Dynamic Internal table with fields from another internal table

[Former Member]

Dear All,

Let me put it straight, if I am having a list of tables from table T682I, field KOTABNR prefixed with 'A',

and the I am able to get the fields for these tables starting with A from DD03L table.

How do I generate an dynamic internal table with all the fields that are selected in internal table same as DD03L, wherein I am selecting multiple tables?

Hope you get it.

Select * from T682I where into internal_table_X where kozgf eq 'PR00'.

then, get KOTABNR from internal_table_X and prefix it with A,

so now I have say, 20 tables with A as prefix,

now for these 20 tables I may get 25 unique fields from DD03L,

Then how do I create a internal table dynamically with all these 25 fields with are decided at runtime.

Awaiting reply and help.

check this example code:

Here is an example code

PARAMETERS : p_table(10) TYPE C.

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.

CREATE DATA w_dref TYPE TABLE OF (w_tabname).

ASSIGN w_dref->* TO <t_itab>.

Hi,

Say you have all the fields in a int tab named it_fields, then

"Declare field cat
DATA: it_fieldcat TYPE lvc_t_fcat.
DATA: wa_fieldcat TYPE lvc_s_fcat.

FIELD-SYMBOLS: <outtab> TYPE ANY TABLE,
                            <l_line>  TYPE ANY.


LOOP AT it_fields INTO wa_fields.
 "fill it_fieldcat from the field name in it_fields.
ENDLOOP.


CALL METHOD cl_alv_table_create=>create_dynamic_table
        EXPORTING
          it_fieldcatalog = it_fieldcat
        IMPORTING
          ep_table        = new_table.

ASSIGN new_table->* TO <outtab>.
CREATE DATA new_line LIKE LINE OF <outtab>.
ASSIGN new_line->* TO <l_line> .

Now <out_tab> is the req int tab with all fields and <l_line> is the work area for it
