In a Business Component, you can specify services associated
with a Logical View. To implement a service, you must declare the
Logical View containing the service request issued by the client component.
Then, you must perform the access to the external resources to check
data consistency and the data items that must be sent to the client
component. The access must be specified in the -CS Lines tab
of the Business Component.
Before you begin
A Business Component must be created in the Server or Server
Dialog editor with a
Business Component Dialog
type.
About this task
A service requires access to several external resources.
The external resources are Segments representing a table, a record,
a file, and so on. These Segments must be associated with the Logical
View that indicates which data must be checked. To implement the access
to external resources, you must declare a Logical View and the Segments
required for the execution of the service. Moreover, you must indicate
the logical and physical characteristics of each Segment.
Procedure
- Open the -CS Lines tab of a Server
or Server Dialog. To do so, select a Server or Server Dialog in the Design
Explorer view and double-click. Otherwise,
right-click and select Open. Then you can access
the -CS Lines tab by clicking directly the -CS
Lines tab. The other possibility is to click More in
the -CS lines section on the Overview tab.
- Then click the button corresponding to the external resource
you want to call in the Business Component: Add Segment, Add
Data Element, Add Server View call or Add
Logical View call. A new empty line is added to the -CS
lines in the table each time you add a new call.
- Enter the code of the Segment (or other resource) and its
characteristics in the -CS lines - Segment call section, -CS
lines - Data Element call section, -CS lines
- Server call section and -CS lines - Logical
View call section so that they show up on the -CS line,
in the columns of the table.
