Validation rules allow ongoing maintenance of data quality.

• Your own business rules can be enforced.

• You can provide tailored error messages to users.

• Rules are defined in a flexible expression language.

The result is a more streamlined reporting process.

• You don’t have to wait until reporting time to fix problems.

• Users can be required to enter data the right way.

• Identifying and fixing problems is easier.

• Rules are attached to tables.• You can set up rules to be enforced

when records are saved.• If a rule is violated, the user is presented

with a custom error message.

Rules can be enforced in two ways

1. When records are saved, users receive error messages.

2. By using the Validate Records option.

Tip: Disabled rules are not validated on save, but can still be checked using the Validate Records option.
