To write a Generic Programming to accept any internal table

Former Member — Sat, 12 May 2007 00:27:41 GMT

Hi Gurus,

<b>By Generic Programming</b>

May I know how to write a form WRITE_TABLE which accepts any internal table and also to write the contents of the internal table to the ABAP list, line

by line and field by field?

Thanks,

Raja

Anyway, I would recommend to use USING or CHANGING by passing the 'body' of the table like this :

*_ User selection

PERFORM user_selection USING s_bname[]

CHANGING wt_bname[].

FORM user_selection USING ps_bname LIKE s_bname[]

CHANGING pt_bname LIKE wt_bname[].

...

ENDFORM. " user_selection

Try this..

PERFORM display TABLES ITAB.

FORM display TABLES LT_TAB.

LOOP AT LT_ITAB.

WRITE: / LT_ITAB.

ENDLOOP.

ENDFORM.

Hi,

if you have input variable lt_itab type any table then you can do something like this:


field-symbols: <row> type any, <field> type any.

loop at lt_itab assigning <row>.

do.

  assign component sy-index of structure <row> to <field>.
  if sy-subrc ne 0. 
*  no more components left in row
  exit. "exit do
  endif.

  if sy-index eq 1.
    write / <field>.
  else.
   write <field>.
  endif.

enddo.

endloop.

Hope this helps,

Björn

Hello Raja

The most generic form of an itab I can think of is a <b>data object</b> referencing the internal table. Perhaps the following sample coding may be useful:

DATA:
  ldo_data    TYPE REF TO data.


" Fill you itab with data (any type)

" Get the data reference of your itab
  GET REFERENCE OF <itab> INTO ldo_data.

" Pass the itab as data reference to your FORM routine
  PERFORM write_table USING ldo_data.


FORM write_table using udo_data  TYPE REF TO data.
* define local data
  
  field-symbols:
    <lt_itab>    TYPE table,
   <ls_line>     TYPE any,
   <ld_fld>       TYPE any.

" De-reference your data object
  ASSIGN udo_data->* to <lt_itab>.
  CHECK ( <lt_itab> IS ASSIGNED ).

  LOOP AT <lt_itab> ASSIGNING <ls_line>.
    DO.
      ASSIGN COMPONENT syst-index OF STRUCTURE <ls_line> TO <ld_fld>.
      IF ( syst-subrc ne 0 ).
        EXIT.
     ENDIF.

"    Do your write statement     
   ENDDO.
  ENDLOOP.

ENDFORM.

Uwe
