This button opens a dialog box displaying information on the current logical entity, such as the name of the software engineer-owner, the dates and times of creation and modification.
This button opens a dialog box for entering a comment text which will be associated with the current logical entity.
If the logical entity is of conceptual origin, the text cannot be modified.
This button opens a dialog box displaying the different applications areas to which the logical entity is attached.
This button opens a dialog box which is used to create (from conceptual properties), modify, delete, sequence or print the logical properties which serve as accesses to a logical entity.
This button opens a dialog box displaying the list of management rules assigned to the logical entity, as well as the list of available management rules which can be assigned to the logical entity.
This button opens a dialog box displaying the list of management rules assigned to the logical entity, in order to resequence this list by modifying the sequence numbers of the listed management rules.

The Enter button (in display mode) closes the dialog box.
The Create button (in creation mode) or Modify button (in modification mode) validates the dialog box.
The various fields of the dialog box are verified. If all are valid, the logical entity definition is updated in the database before the box is closed; otherwise, an error message is displayed.
This button closes the dialog box without validating the choices made.
However, the operations performed on properties are not cancelled.
If a logical entity creation is cancelled, the possible comment and the logical properties are deleted, and the management rules are de-assigned.
