Hi srihari,
for better responses make every questiion as a new post.
<u><b>2. diffrence between list & grid.</b></u>
1. For all practical purposes, they are the same.
2. 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><b>4. diffrence between table & template</b></i>
Template is a static content so that itz layout cannot be changed dynamically.Eg.Tax forms etc..
Table is a dynamic content whose layout doesn't have fixed size ie.dynamic..eg..internal table contents..
<i><b>7. diference between check table & value table.</b></i>
A foreign key links two tables T1 and T2 by assigning fields of table T1 to the primary key fields of table T2. Table T2 is then known as the check table of the foreign key.
value table : when you define a domain, you already know that all fields that use the domain will need to be checked against a particular table. You can store this information in the domain definition by specifying a value table.
If you try to define a foreign key for a field that points to this domain, the value table of the domain is proposed as the check table for the foreign key.
