Creating a User Buffer

In the Server Dialog, you can define a user buffer to complement the technical buffer.

About this task

The message between client and server components can include information related to the execution of the called service. The user buffer is used to position additional fields which complement the technical buffer (data compression, identification of the user...).

You must define the structure of this information and the processing of its content in a Segment, which represents the user buffer.

This structure is included in each message exchanged between all the Business Components of the Dialog and the client components.

Procedure

  1. Open the-CS Lines tab of a Server Dialog. To do so, select a Server Dialog in the Design Explorer view and double-click it or select Open in the pop-up menu. Then access its -CS Lines tab from the Overview tab or directly by clicking the -CS Lines tab.
  2. Call the Segment which constitutes the user buffer and specify W in Organization. The Business Components of a Folder (root and depending nodes) must use the same Segment to define a user buffer. In graphic applications, a user buffer does not have any repeated Data Element or FILLER Data Element.
