To define a Logical View, you must indicate the number
of Logical View instances and the transfer direction between the client
and the server.
To open a Logical View editor, click the Segment entity folder
in a location within the
Design Explorer view,
and select a Logical View occurrence.
Note: All the data-entry
fields included in the Logical View Definition tab are required.
- Number of occurrences
- The value entered in this field specifies the read or update iterative
capacity of a server that calls this Logical View. This capacity is
expressed by a maximum number of repetitions. The Logical View can
then be used as a repeated structure. The maximum number is 999 occurrences.
Note: If the Logical View is not a repeated structure as a whole and if
only a few of the Data Elements which constitute it belong to a repeated
structure, it must be specified in the Data type field, in the -CE Lines tab. For more explanations,
read the online help available on the -CE Lines tab in the Logical View editor.
- Transfer direction
- In a Logical View which is a repeated structure (previous field
specified), it represents the transfer direction between the client
and the server:

Default value for an update service or a selection
service. It is the required value for graphic applications. |
C: Client to Server |
Client to Business Component: From the Logical
View to the Segment for an update service. |
S: Server to Client |
Business Component to client: From the Segment
to the Logical View for a selection service. |
Note: You only select C or S if all the Data Elements have the same transfer direction. Otherwise
specify it in the -CE Lines tab of the Logical
View editor.
