Hi,

If you look at the parameters,you can see more options in GRID.The following are those extra options which you cannot see in LIST.

I_CALLBACK_TOP_OF_PAGE = ' '

I_CALLBACK_HTML_TOP_OF_PAGE = ' '

I_CALLBACK_HTML_END_OF_LIST = ' '

I_STRUCTURE_NAME =

I_BACKGROUND_ID = ' '

I_GRID_TITLE =

I_GRID_SETTINGS =

IT_ALV_GRAPHICS =

IT_ADD_FIELDCAT =

IT_HYPERLINK =

I_HTML_HEIGHT_TOP =

I_HTML_HEIGHT_END =

IT_EXCEPT_QINFO =

If the caller specifies an EXIT routine, this routine must have the following form:

FORM top_of_page.

Module REUSE_ALV_COMMENTARY_WRITE can then be called within the EXIT routine. This module is responsible for formatting the header information and also ensures online HTML formatting. In the print preview or in batch mode, the text passed is then output in the normal format.

If module REUSE_ALV_COMMENTARY_WRITE cannot be used, you must use two parameters instead. In I_CALLBACK_TOP_OF_PAGE you pass the form routine that is responsible for normal formatting in batch mode or in the print preview mode. The form routine that is responsible for online formatting, is passed in parameter I_CALLBACK_HTML_TOP_OF_PAGE. If one of these parameters is not filled, top-of-page is not output in the respective mode.

In function module documentation,if you click those parameters,you can see the explanation.

If you need more information,get back.Otherwise,kindly close the thread by rewzarding points for useful replies.

HI,

a)Grid cannot handle high volumes.

b) Alv grid (using oo concept) requires

designing the screen layout .

Hence, in one screen, we can show more

then one alv grid

(we cannot show more than

one alv list on one screen)

c) ALV grid uses ActiveX controls

present on the Presentation Server.

Hence, it consumes More Memory

on the presentation server.

d) ALV LIST is Display Only.

Whereas ALV Grid Can Be made EDITABLE for entry purpose.

e) In alv grid, these options are possible,

but not in alv list.

without horizontal lines

without vertical lines

without cell merging during sorts

display total lines above the entries

ALV LIST Can be coded using only FMs

ALV GRID Can be coded using FMs and object oriented concepts

ALV LIST Can be displayed hieraicharlly

ALV GRID cannot be displayed hierarichally

Padmam.

As you can see, at last in SAP BASIS 6.20, 'REUSE_ALV_LIST_DISPLAY' does not have parameters that are not in 'REUSE_ALV_GRID_DISPLAY' ,

Hope it helps,
