As noted, LANSA can automatically generate field level help text in the correct language for the user. The help text is derived from the Repository and includes the field definition information, as well as information regarding the validation rules. Automatic help text generation can be disabled at either the system or the field level.
When editing a field definition, you can create help text by using the Repository Help Tab in the Visual LANSA User Guide. The text is entered directly using the Repository Help Editor. If the field uses a reference field, you can import the help text from the reference field.
