Hi,

Its just the look and feel.

The grid has a better look. But it cannot be displayed in background mode(in spool).

Check the outputs of the sample programs:

BALVEX01(for list)

and BCALV_TEST_GRID(Grid)

Regards,

Priyanka.

Hi,

both REUSE_ALV_LIST_DISPLAY,REUSE_ALV_GRID_DISPLAY are same but the o/pstructure is different.

in REUSE_ALV_GRID_DISPLAY we can give the title but in list it is not possible.

in GRID editiing rows is possible whereas in list it is not possible.

1)REUSE_ALV_LIST_DISPLAY --- when we use this fun module,then it is like a static list, means, u cannot do these operations

-- hide

-- change the order of coloumns

-- total

2) REUSE_ALV_GRID_DISPLAY --- when we use this , it will have all the above features mentioned...

<b>When there are no editable fields u can simply use LIST DISPLAY else go for GRID

When you want to run in background go for LIST else GRID</b>

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,

1) REUSE_ALV_LIST_DISPLAY

to display o/p list ina normal form with no graphical represntations like adding colors, having no user defined field names for fields, confirmation messages for deleting a field..........

2) REUSE_ALV_GRID_DISPLAY

to display o/p in graphical manner with different options with the help of various FM's like

REUSE_ALV_FIELDCATALOG_MERGE [ for buliding a structure o/p ]

REUSE_ALV_EVENETS_GET [ for diff alv events]

REUSE_ALV_COMMENTARY_WRITE [ for having a logos, images ]

REUSE_ALV_VARIANTS_DEFAULT [ for variants]

....................

................

if helpful reard some points.
