Object oriented programming with header

Former Member — Wed, 11 Dec 2013 06:20:22 GMT

Hi,

Can I display two header in the same ALV output? I have been trying with no success. I am using two table ;

TABLE1 : VBAK and TABLE : VBAP.

Please check my code.

Thanks in advance.

Re: Object oriented programming with header

Hi Raj,

You can try to define two layouts:

DATA: l_layout TYPE lvc_s_layo,

l_layout2 TYPE lvc_s_layo.

l_layout-grid_title = 'Table 1'.

l_layout2-grid_title = 'Table 2'.

CALL METHOD go_grid1->set_table_for_first_display

EXPORTING

i_structure_name = 'VBAK'

is_layout = l_layout

CHANGING

it_outtab = It_VBAK

EXCEPTIONS

OTHERS = 4.

CALL METHOD go_grid2->set_table_for_first_display

EXPORTING

i_structure_name = 'VBAP'

is_layout = l_layout2

CHANGING

it_outtab = it_vbaP " empty !!!

EXCEPTIONS

OTHERS = 4.

Hi Raj,

if you use this factory method, and you add it to your container:


DATA lo_alv_vbak TYPE REF TO cl_salv_table.
DATA lt_vbak TYPE STANDARD TABLE OF vbak.


* Perform your vbak selection
* Perform your splitter / container story

cl_salv_table=>factory(
  EXPORTING
    r_container  = o_top_container
  IMPORTING
    r_salv_table = lo_alv_vbak
  CHANGING
    t_table      = lt_vbak ).

Then you can use the LO_ALV object instance to create a header for each alv:


DATA lo_header TYPE REF TO cl_salv_form_layout_grid.
DATA lo_label TYPE REF TO cl_salv_form_label.

CREATE OBJECT lo_header.
lo_label = lo_header->create_label( row = 1 column = 1 ).
lo_label->set_text( 'This is my label for VBAK' ).
lo_alv_vbak->set_top_of_list( lo_header ).

And you can have another object instance - or reuse the above ones, for your other header.

Best,

Sander

Thanks for help.

But I want PAGE HEADER like TOP-OF-PAGE.

Re: Object oriented programming with header

former_member192854 — Fri, 13 Dec 2013 13:55:52 GMT

Hi Raj, are you sure this is not like TOP-OF-PAGE?

Best,

Sander

Re: Object oriented programming with header

Former Member — Mon, 16 Dec 2013 06:07:52 GMT

Yes, I'd like to trigger TOP_OF_PAGE event in an ALV report using CL_GUI_ALV_GRID class. I would also like to use the object of class CL_DD_DOCUMENT.

Please help me with a sample code as i'm a fresher.
