Hi Kaladhar,
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
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.
