Group Types

Group types allow you to organize your groups in different categories and associate certain metadata with a group.

group type object

Properties

Each group type has the following properties:

Property	Description
Name	The name that is used when referencing the group type. This name can also be returned when querying the groupTypeName property using the `group()` function. Follow the recommended naming standard when creating this name.
Description	(Optional) Information about the group type that is displayed in the objects grid of some Designer views.
Attributes	Additional metadata that can be configured about the groups of this type.

All group type properties are configured through the Properties dialog. It can be accessed in one of two ways:

From the toolbar in Appian Designer
From the gear menu when viewing a group type

Group type attributes

Attributes are custom fields that provide additional information about groups of that type. This allows you to further differentiate groups from each other and use the associated metadata throughout your application.

Some types of attributes require each group within the group type to have a value. Attributes of that type require a default value to be set when adding the attribute.

Attribute data types

Group type attributes can be of the following types:

Type	Value Required
Boolean	Yes
Date	Yes
Group	No
Number (Decimal)	Yes
Number (Integer)	Yes
Text	Yes
User	No

Configuring attributes

Once an attribute has been added to a group type, its configuration cannot be edited. Attributes can be removed by the creator of the group type or by a system administrator.

Creating groups

When viewing a group type, you can create a new group of that type using the New Group button in the toolbar. The Group Type configuration will automatically be defaulted to the current group type.

Security

Tip: Unlike most objects, group types do not have their own security role maps. When groups that are members of a group type are invoked, group security is applied instead.

Only system administrators and designers can perform actions on group types. The following table outlines the group type actions that can be completed by each:

Actions	System Administrator	Designer
Create a group type	Yes	Yes
View the group type	Yes	Yes
Edit name	Yes	No¹
Edit description	Yes	No¹
Add new attributes	Yes	No¹
Remove attributes	Yes	No¹
Create groups of this type	Yes	Yes

Designers can only perform these actions if they originally created the group type. ¹ ² ³ ⁴
