Creating Database ViewsBy Pranshu Kukreti,
InfosysIntroductionDatabase views are used to combine application
data often distributed over several tables. The structure of such
views is defined by specifying the tables and fields that are
required. Fields which are not required can be hidden, thereby
minimizing the interfaces. A view can be used in ABAP programs for
data selection.Following demo shows how to create database view for
two database tables having foreign key relationship.We will be
creating a database view for below shown tables YZ14_BANK &
YZ14_ACCOUNTS. Note that YZ14_ACCOUNTS is foreign key table
(dependent table) and YZ14_BANK is check table (referenced table)
for field BRANCH_ID. It should be kept in the mind that we can only
include transparent tables in database view.Steps1.Go to
transaction SE11 -> select radio button 'View' -> enter the
name of the view -> press 'Create'.2.Below pop up screen will be
displayed. Select 'Database View' and pressbutton.3.Below screen
gets displayed, enter suitable short description.4.In 'Tables'
enter the name of the base tables which we want to include in our
view. In this case we will be entering tables as YZ14_BANK &
YZ14_ACCOUNTS.
5.Next, we need to link the entered tables by specifying the
fields in join condition. We can also derive the join conditions
from existing foreign keys between the base tables of the view. To
do this, position the cursor on the table names and click onpresent
at the bottom.6.Below pop up comes wherein linked tables are
present. Select the tables and press 'Copy'.7.On clicking copy
button, join condition will be derived from the base tables. In our
case, we have the below shown conditions.8.In the 'View Flds' tab,
we need to enter all the fields, we want in our view from the
database tables. We can either enter the fields directly or we can
copy them from base tables. Later can be achieved by pressingbutton
present in the tab 'View Flds'. We can also include complete table
in a view by entering*in 'View field' & table name in 'Table'.
If fields are inserted or deleted from this table, similar
modification will be automatically made in view structure.
