Hi,

Don't make your thread with Multiple Questions.

BLOCK ALV is used for Multiple Lists.

Difference Between Alv grid and List Display :

Some differences:

a) from abap coding point of view,

alv list is done with Function modules,

alv gris can also be done with FM,

but can also be done using OO concepts.

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

Hi,

To put default values to parameters or select-options use this..

parameter: p_matnr like mara-matnr default 'test1'..

select-options: s_matnr for mara-matnr default 'test1' to 'test2'.

or u can do it in INITIALIZATION event assigning values to it.

INITIALIZATION.

p_matnr = 'test3'.

s_matnr-low = 'test4'.

s_matnr-high = 'test5'.

s_matnr-sign = 'I'.

s_matnr-option = 'BT'.

append s_matnr.

if you want to display those 2 fields only, create your own fieldcatalog. and pass it to it_fieldcat export parameter in the reuse...... FMs.

Reward if useful.

Hi,

1)In ALV list display it only display the list u can not drag and drop to ur output fileds , but where as in grid display in the out put u can drag & drop the list fields.

2)difference between list display & block display.

List display it display the list out put.

But block display it will display block wise output.

ex: in block display u have 2 internal table like kna1,mara.

O/P : 1) kunnar name1 land1

2) matnr mbrsh

where as in list display it will display.

kunnr name1 land1 matnr mbrsh

it display the contents like that.

3) ur getting 5 fileds instead of 2 fileds.

i think ur passing structure in list display function module .

try to use filed catalog and pass it to list display FM.

other wise i_output = just u pass internal table.

reward me a points if it is use full answer/
