Hi osk,

1. In programs we can use

views (Database views / Projection Views)

only

2. bcos

3. Such views are ACTUALLY

created in physical database

and hence, database itself supports

select * from

such views.

4. however, maintenance views,

(as the name suggests)

are merely COLLECTION OF SCREENS

to facilitate dataentry

in the table(s)

in a well defined manner.

(There is no physical view in the database)

Hence, we cannot use such views in programs.

4. PROJECTION VIEW

Its nothting but a NORMAL view

with ONLY 1 table,

and selected fields only (not all fields)

from the table.

Hi,

Help View ( SE54)

Help views are used to output additional information when the online help system is called.

When the F4 button is pressed for a screen field, a check is first made on whether a matchcode is defined for this field. If this is not the case, the help view is displayed in which the check table of the field is the primary table. Thus, for each table no more than one help view can be created, that is, a table can only be primary table in at most one help view.

Projection View

Projection views are used to suppress or mask certain fields in a table (projection), thus minimizing the number of interfaces. This means that only the data that is actually required is exchanged when the database is accessed.

only for single table and used to suppress certain fields of a table.Base tables are accesssed via R/3 system.
