Attributes of Fields on Default Forms
Vision assigns attributes to fields on the default form as follows:
You cannot display the join field in the Detail table.
Any field in the Master or Detail table that activates a Lookup table is created as a mandatory field (that is, the user must make an entry in this field).
Lookup table columns that you display as fields on the form are:
Query-only for simple fields
Display-only for table fields
Sequenced fields in Append frames are created as query-only.
Columns in a Master or Detail table that are not null not default are created as mandatory fields.
All Master and Detail table columns that you include in the visual query are created as restricted fields; that is, you cannot:
Change the field's internal name
Change the field's data type
Delete the field from the form
The default form can change when you modify the frame definition. You can also use Vision's forms editor to modify a Vision-generated form. For more information on using the Vision forms editor, see Editing a Form.
