HI Sai,

It is simple. I hope u have two internal tables like details and summary.

END-OF -SELECTION.

IF po_details EQ 'X'.

Build field catelog for 8 fields(Those displayed when u select details radio button).

Now call reuse ALV fm with details internal table.

ELSE.

Build field catelog for 3 fields(Those displayed when u select summary radio button).

Now call reuse ALV fm with summary internal table.

ENDIF.

If u dont have two internal tables then u have to change the logic such that u have two internal tables. One for details and other for summary.

Thanks,

Vinod.

Hello Sai

Assuming that both lists - detailed and summary - have the same fieldcatalog but should display different numbers of columns the correct approach is as following:


FORM build_fieldcatalog.
* define local data
  data: ls_fcat    TYPE lvc_s_fcat.

" NOTE: GT_FCAT contains the columns of your ALV list.

" User chooses detailed list (p_opt1 = 'X') -> display all columns
" User chooses summary list (p_opt2 = 'X') -> display only three columns

  CHECK  ( p_opt2 = 'X' ).

  LOOP AT gt_fcat INTO ls_fcat
                            WHERE ( fieldname = 'COLUMN4'   or
                                           fieldname = 'COLUMN5'   or
                                          ... ).  " list columns to be hidden
    ls_fcat-tech = 'X'.  " completely hide from user
    MODIFY gt_fcat FORM ls_fcat INDEX syst-tabix.
  ENDLOOP.

ENDFORM.

Regards

Uwe
