Using Input Masks to Set Up Field Formats

Some forms contain fields in which you can specify an input mask, or template, that determines the format used to display or enter values in the field.

Note: In specifying an input mask, consider whether a null value is allowed in a field. To prevent the system from attempting to save an unspecified value in a decimal field bound to a table column that does not allow null values, use the mask character 9. An input mask that contains 9 defaults to 0 if no value is specified in the field, and the value 0 can be saved.
