Rational Programming Patterns

Logical View Definition tab

To define a Logical View, you must indicate the number of Logical View instances and the transfer direction between the client and the server.

All the fields must be entered.
Number of occurrences
The value 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 that constitute it belong to a repeated structure, it must be specified in the Data type field, in the CE Lines tab.
Transfer direction
In a Logical View that is a repeated structure, it represents the transfer direction between the client and the server:
Table 1. Specification of the transfer direction
Options Comments
Both directions Default value
C: Client to Server Transfer from the Logical View to the Segment for an update service.
S: Server to Client Transfer 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 Lignes -CE tab of the Logical View editor.
