Working with domains

You use domains to select or enter valid values for certain fields. The defined values are specified by domains. Many domains are used in the product's applications.

In some cases, you can specify error messages that users see when an invalid value is entered.

Work with the application in your nonproduction environment, and then import the changes to your production environment.

If you add or modify a domain, existing records are not validated or changed unless a user edits the value in a field. Your users are helped to enter valid values by the information that you specify in the Attribute Description field.

A new domain can be linked to an attribute in the Database Configuration application. Domains can also be specified on classification attributes to provide pick lists for users. Domains that are added to classification attributes do not require further configuration.

When a field is linked to a domain, you can show a lookup indicator on the field. Configure that control to specify a lookup list in Application Designer. The lookup definition and format are defined in the Lookups.xmlfile. In Lookups.xml, you can add lookups to select the displayed columns, and can add sorting and filtering as you require. You can export the Lookups.xml file from Application Designer, modify it, and import and test the changes.

Work with these applications in your nonproduction environment, and import the changed files to your production environment.
