The data flow is automatically generated from the data specified when the windows were defined.
To work with the logical entities assigned to a window:
either select the Work with logical entities option from the Layout menu in the Visual Adelia layout manager for a VADELIA program,
or select the Logical entities option from the context-sensitive menu of a page in a WADELIA program tree view.
You can specify the following elements:
the access type used, when a list is loaded,
the properties constituting the access to the information selected in a given entity.
See the explanations for the following dialog box:
- Work with logical entities in the Visual Adelia layout manager or in the 4GL Editor for a WADELIA program.
