Using ListChoices Without a Lookup Table
Vision generates a ListChoices menu item for each Append, Browse and Update frame (except as described immediately above). If you do not include a Lookup table in a frame definition, the ListChoices operation functions as follows:
• If you use the Visual-Forms-Editor to specify a validation for any fields on the form, Vision checks this validation when a user selects ListChoices.
For example, you can specify a validation to make sure that the customer number that a user enters is a current value from the Customers table. See Character-based Querying and Reporting Tools User Guide for details on VIFRED validations.
• If you do not specify a validation, Vision displays a message informing the user that ListChoices is not a valid operation for the field.
