## Attribute Types

There are ten attribute types, as shown below. The type determines what values are acceptable and how the attribute is used.

- Text--The attribute value is a string of text.

- Number--The attribute value is a number with the optional format mask you specify.

- Date--The attribute value is a date with the optional format mask you specify.

- Lookup--The attribute value is one of the lookup code values in a specified lookup type.

- Form--The attribute value is an Oracle Applications internal form function name and its optional form function parameters. This attribute type is not relevant for the standalone version of Oracle Workflow.

If you include a form-type attribute in a notification message as a message attribute, the notification, when viewed from the Notification Details web page, displays an attached form icon that lets users drill down to the referenced form. See: Overview of Menus and Function Security, Oracle Applications Developer's Guide.

- URL--The attribute value is a Universal Resource Locator (URL) to a network location. If you reference a URL attribute in a notification message as a message attribute, the notification, when viewed from the Notification Details web page or as an HTML-formatted e-mail, displays an anchor to the URL specified by the URL attribute. The user can complete an activity or see additional information related to the activity by accessing that URL.

- Document--The attribute value is an attached document. You can specify the following types of documents in the default value field:

- PL/SQL document--a document representing data from the database, generated from a PL/SQL procedure.

- DM document--a document managed by an external document management system.

See: To Define a Document Attribute.

- Role--The attribute value is the internal name of a role. If a message attribute of type role is included in a notification message, the attribute automatically resolves to the role's display name, eliminating the need for you to maintain separate attributes for the role's internal and display names. Also when you view the notification from a web browser, the role display name is a hypertext link to the e-mail address for that role. To set a default value for the attribute, you must initially load roles from the database. See: Roles.

- Attribute--The attribute value is the internal name of another existing item type attribute that you want to maintain references to in a process.

- Event--The attribute value is a Business Event System event message in the standard WF_EVENT_T structure. See: Event Message Structure.
