Hi,

(1) REUSE_ALV_LIST_DISPLAY

Display an ALV list as per parameters defined in the function call

(2) REUSE_ALV_GRID_DISPLAY

Display an ALV grid as per parameters defined in the function call

(3) REUSE_ALV_COMMENTARY_WRITE

List header information is output according to its type. The output information is put in an internal table. Output attributes are assigned to each line via the TYP field.This module outputs formatted simple header information at TOP-OF-PAGE.

(4) REUSE_ALV_HIERSEQ_LIST_DISPLAY

This module outputs two internal tables as a formated hierarchical-sequential list.

(5) REUSE_ALV_VARIANT_F4

Display variant selection dialog box.

(6) REUSE_ALV_VARIANT_EXISTENCE

Checks whether a display variant exists.

hi

Grid cannot handle high volumes.

) 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

For all practical purposes, they are the same.

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

I hope it helps.
