Adding/modifying Segment calls

The Segments calls are used for the processing of data external to the Screen. For each Segment, you must indicate its physical characteristics (type of organization...) and type of use (read, update...) in the -CS lines tab of the Screen editor.

To add a Segment call, you must:
  1. Open the -CS Lines tab of a Screen. To do so, select a Screen in the Design explorer view of the Design perspective and double-click on it or select Open in the popup menu. Then access its -CS Lines tab from the Overview tab or directly by clicking the -CS Lines tab.
  2. Click the Add Segment button. A selection box opens up with the list of the Segments available in the location.
    1. If the Segment you want to call is displayed in this selection box, just click on its corresponding checkbox.
    2. If it is not displayed, just click on the New Segment button in the selection box. In the creation wizard which opens up, enter the name and label of a new Segment and click OK. The new Segment is then displayed in the selection box. If you select it and click OK, it will be called in the -CS Lines.
  3. Then you need to enter information on the Segment such as the id, logical characteristics, access key, primary key, and physical characteristics. To do so, click a Segment in the -CS lines, and complete the different fields in the CS lines - Segment call section.
To add or modify Data element calls in a Segment, the procedure is the same but you click the Add Data element button and enter the required parameters in the CS lines - Data element call section.
