create data reference to a table that is known at runtime

Fabian_Kegel — Fri, 09 Jun 2006 13:54:26 GMT

Hi,

I am trying to create a data reference to a table that is known only at runtime. In system 4.6C, I am not able to insert this coding

data: lr_data type ref to data.

CREATE DATA lr_data type table of (structure_name).

In hihger releases, I am able to do so.

Could you please tell me how to solve this problem in 4.6C?

Best regards,

Fabian

Hi Fabian

May be the data reference to a table is not possible in versions below 4.7E. So is why you are unable to do that.

Hi fabian,

If i understood,

u want to create a dynamic internal table.

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

amit m.

I'm working on 4.6C and that statament isn't supported here, but only from 4.7.

In 4.6C you can use the class CL_ALV_TABLE_CREATE
