Define workarea runtime from structure

Former Member — Tue, 24 Jul 2007 12:04:54 GMT

Hi,

How is a work area defined runtime from a structure? I would like to read the name of the structure from db table. Then use that structure to define a work area.

I have tried the following.

data:

struc_name type abap_typename,

structure_name(25) type c.

structure_name = 'ZDKD0001INSTALMENTS'.

move structure_name to struc_name.

data:

wa_structure type struc_name.

Hope anyone can help.

Regards,

Morten

as u are hard coding your structure name the runtime concept never comes in to picture here

Hi,

Just click on the below link.

Here you can see the complete details of HOW TO CREATE DYANMIC INTERNAL TABLE( Defining structure at runtime ). It is Crystal Clear.

Hi morten,

For this purpose,

in my program,

there is an INDEPENDENT FORM

whose inputs are

TABLE NAME / STRUCTURE NAME

and from those, it consructs dynamic table.

2. Here is the program.

the dynamic table name will be

<DYNTABLE>.

3. U can use this program (FORM in this program)

to generate any kind of internal table

by specifying TABLE NAME .

REPORT abc.

*----

COMPULSORY

FIELD-SYMBOLS: <dyntable> TYPE ANY TABLE.

FIELD-SYMBOLS: <dynline> TYPE ANY.

DATA: lt TYPE lvc_t_fcat.

DATA: ls TYPE lvc_s_fcat.

FIELD-SYMBOLS: <fld> TYPE ANY.

DATA : fldname(50) TYPE c.

*----

parameters : iname LIKE dd02l-tabname.

*----

START-OF-SELECTION.

*----

PERFORM

PERFORM mydyntable USING lt.

BREAK-POINT.

*----

INDEPENDENT FORM

*----

FORM mydyntable USING ptabname.

*----

Create Dyn Table From FC

FIELD-SYMBOLS: <fs_data> TYPE REF TO data.

FIELD-SYMBOLS: <fs_1>.

FIELD-SYMBOLS: <fs_2> TYPE ANY TABLE.

DATA: lt_data TYPE REF TO data.

data : lt TYPE lvc_t_fcat .

DATA : ddfields LIKE ddfield OCCURS 0 WITH HEADER LINE.

*----

CALL FUNCTION 'DD_NAMETAB_TO_DDFIELDS'

EXPORTING

tabname = iname

TABLES

ddfields = ddfields.

*----

CONSTRUCT FIELD LIST

LOOP AT ddfields.

ls-fieldname = ddfields-fieldname.

APPEND ls TO lt.

ENDLOOP.

ASSIGN lt_data TO <fs_data>.

CALL METHOD cl_alv_table_create=>create_dynamic_table

EXPORTING

it_fieldcatalog = lt

IMPORTING

ep_table = <fs_data>

EXCEPTIONS

generate_subpool_dir_full = 1

OTHERS = 2.

IF sy-subrc <> 0.

ENDIF.

*----

Assign Dyn Table To Field Sumbol

ASSIGN <fs_data>->* TO <fs_1>.

ASSIGN <fs_1> TO <fs_2>.

ASSIGN <fs_1> TO <dyntable>.

ENDFORM. "MYDYNTABLE

regards,

amit m.

Hi,

Try way.

TYPE-POOLS ABAP.

DATA: STRUC_NAME TYPE ABAP_TYPENAME.

DATA: TABLEMARA TYPE TABLE OF MARA.

FIELD-SYMBOLS <FS_WA> TYPE ANY.

START-OF-SELECTION.

STRUC_NAME = 'TABLEMARA'.

ASSIGN (STRUC_NAME) TO <FS_WA>.

....

or.

DATA: DATA_OBJ TYPE REF TO DATA.

FIELD-SYMBOLS <FS_WA> TYPE ANY.

START-OF-SELECTION.

CREATE DATA DATA_OBJ TYPE MARA.

ASSIGN DATA_OBJ->* TO <FS_WA>.

Regards.

data: wa_ref type ref to data.

field-symbols : <wa_fs> type any.

during run time call..

CREATE DATA wa_ref TYPE (MARA). " To create wa like data dictionary table or structure

CREATE DATA wa_ref LIKE LINE OF itab. " To create wa type of some internal table.

then

use..

ASSIGN wa_ref->* TO <wa_fs>.

then u can use <wa_fs> as work area for internal table or some type..

Reward if useful
