Using the Formula Field
Field Description
Using the Data Designer
Validation Select the kind of validation to apply to this field. Your
choices are:
No validation - the user’s response is not checked
Non-negative number (required) - the result of
the calculation must be a positive number
Custom - You can create custom validation. For
more information, see ”Custom Validation” on
page 409.
If you assign to this field any value other than No
validation, the field is surrounded by red dashes in
Data Entry mode. If the user’s response does not meet
the validation criteria, the field remains surrounded by
red dashes. Your system administrator determines if a
user can save a screen with invalid data.
Caption Enter text to describe this item on the data entry screen.
After you insert this field onto the screen, you can use
eWebeditPro+XML’s formatting capabilities to modify
its size, font, color, and other attributes.
Note: The Caption field only appears on this dialog
when you create the Calculated field. If you later try to
edit the field, the Caption field is not on the dialog.
However, you can edit the Caption text within the editor.
You can copy a sample calculation into the Formula field by
clicking the Examples field and selecting an operation from the
drop down list. For example, if you click on Examples Add two
numbers (X+Y), {X}+{Y} appears in this field.
