Increase ALV Header length

[Former Member]

Hi,

Does anybody know, How to increase the Header length in ALV Report?

The standard function module and class holds the length upto 70 Characters.

The FM - REUSE_ALV_GRID_DISPLAY has the parameter called 'I_GRID_TITLE' and it referes the data type 'LVC_TITLE'. When I increased this length to 255 in FM as well as in the class 'CL_GUI_ALV_GRID'. It did not display. Is there any other way to increase the length?

Thanks,

Ramesh

U may not be able to increase the length of the column header.

IF cl_gui_alv_grid=>offline( ) IS INITIAL.

    CREATE OBJECT o_dockingcontainer
      EXPORTING
<b>        ratio                       = '95'</b>
     EXCEPTIONS
      cntl_error                  = 1
      cntl_system_error           = 2
      create_error                = 3
      lifetime_error              = 4
      lifetime_dynpro_dynpro_link = 5
      others                      = 6.

    IF sy-subrc NE 0.
*      MESSAGE i001 WITH text-e01.
      LEAVE LIST-PROCESSING.
    ENDIF.

  ENDIF.

This is the max size of the docking container.

U can specify in the layout

FORM f9400_layout.

  w_layout-grid_title = sy-title.
  w_layout-zebra      = 'X'.
  w_layout-sel_mode   = 'B'.
 <b> w_layout-cwidth_opt = 'X'.</b> (Autamatically set the width according to the length of the header)
  w_variant-report    = sy-repid.
 ENDFORM.                    " f9400_layout

Hope this helps u.

First of all - I would NOT change any of these objects!! You are changing SAP core and placing your implememtation at great risk as this code is run by hundreds/thousands of programs.

I would start by making a clone of all objects (including the LVC_TITLE) as Z or Y objects.

From there... make sure that data element LVC_TITLE is tied to a domain of greater than 70 chars long. You can create a custom domain of your liking as well for this.

Hi Ramesh,

Function REUSE_ALV_GRID_DISPLAY has a Parameter I_CALLBACK_HTML_TOP_OF_PAGE

You can use this parameter to display a header of arbitrary length.

See SAP Demo BCALV_VERIFY_DATATYPES, especially Form Routine F01_ALV_EVENT_HTML_TOP_OF_PAGE for the methods creating extended header.

All,

Thanks Guys for the related answers.

Actually BCALV_GRID_01 this standard SAP report does the same work what I was trying to. We need to design the screen in such a way. i. e in the top, Design the Fields to show and in the bottom create custom control.

Using the Method SET_TABLE_FOR_FIRST_DISPLAY I was able to bring the result.

Once again thanks a lot guys.

Thanks,

Ramesh

Hi,

1. Instead of TOP_OF_PAGE event, use I_CALLBACK_HTML_TOP_OF_PAGE and CL_DD_DOCUMENT to add header content.

2. Use FM RSDG_WORD_WRAP to split the lengthy lines into multiple smaller ones and pass it to REUSE_ALV_COMMENTARY_WRITE.

Best regards, Sudhakaran
