Dynamic internal table declaration

[Former Member]

Hi ,

I am writing a report to display table contents in report output, all are Z- Tables and small tables. Selection screen input is Table name.

In the program how can i declare a internal table dynamically and also how can i assign the values to internal table in select statement ?

SELECT * FROM (P_TABLE) INTO ?????
          WHERE (OPTIONS).

Thanks,

Fract

Hi,

Try this...

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>.

select *

from (w_tabname) up to 20 rows

into table <t_itab>.

(code}

Sample code snippet:

REPORT ZDYNA . 

DATA: d_ref TYPE REF TO data, 
d_ref2 TYPE REF TO data , 
i_alv_cat TYPE TABLE OF lvc_s_fcat, 
ls_alv_cat LIKE LINE OF i_alv_cat. 


TYPES tabname LIKE dcobjdef-name . 
parameter: p_tablen type tabname. 

data: begin of itab occurs 0. 
INCLUDE STRUCTURE dntab. 
data: end of itab. 


FIELD-SYMBOLS : <F_FS> TYPE table, 
<F_FS1> TYPE TABLE, 
<F_FS2> TYPE ANY, 
<F_FS3> TYPE TABLE. 

REFRESH itab. 
CALL FUNCTION 'NAMETAB_GET' 
EXPORTING 
langu = sy-langu 
tabname = p_tablen 
TABLES 
nametab = itab 

EXCEPTIONS 
no_texts_found = 1. 
LOOP AT itab . 
ls_alv_cat-fieldname = itab-fieldname. 
ls_alv_cat-ref_table = p_tablen. 
ls_alv_cat-ref_field = itab-fieldname. 
APPEND ls_alv_cat TO i_alv_cat. 
ENDLOOP. 
* internal table build 
CALL METHOD cl_alv_table_create=>create_dynamic_table 
EXPORTING it_fieldcatalog = i_alv_cat 
IMPORTING ep_table = d_ref . 
ASSIGN d_ref->* TO <F_FS>. 

SELECT * FROM (p_tablen) INTO CORRESPONDING FIELDS OF TABLE <F_FS>. 


LOOP AT <F_FS> ASSIGNING <F_FS2>. 
*your code goes here. 
ENDLOOP.
