Common class attributes you can define in Class Manager

Data Type

The type of information that the attribute contains. After you select a data type, data type characteristics fields specific to your selection appear on the right of the Data Type field.

Attribute Name

A descriptive name of up to 80 alphanumeric characters (including underscores) that is indicative of the function.

Note: There is no mechanism in Class Manager to specify a localized label to appear in place of the Attribute Name on the class form. To change the label, use BMC Remedy Developer Studio to create or edit the appropriate view of the class form.

Namespace

Namespace for the attribute. Select or enter a namespace if this attribute should be in a different namespace than the class that contains it. To use the class namespace, leave this field blank.

Field ID

ID of the field created for the attribute on the class form. It is an integer that must be greater than 536870911 but less than 2147483647, which is the default maximum value for field IDs. If you want the system to generate an ID, leave this field blank.

Entry Mode

Mode that determines whether the attribute must contain a value for each instance and whether its value is stored in the database. It can be any one of these options:

• Required — The attribute value must be filled in when a user creates an instance. A required attribute appears with a bold label in the class form.
• Optional — You can enter information for the attribute or leave the field empty.
• Display only — The attribute is used as a temporary field. The value of the attribute is not stored in the database.

Audit Option

An option that determines whether changes to this attribute value trigger an audit:

• Audit — Changes to the value trigger an audit.
• Copy — Changes to the value cause the attribute to be written to the audit form.
• Audit and Copy — Changes to the value trigger an audit and cause the attribute to be written to the audit form.
  The default is None.

Attribute Type

The type of the attribute, either regular or core. You can create only regular attributes.

Custom Properties

Additional information about the attribute. You must enter the custom properties in the following format:

{ “fieldID1”: <value1>}

For example, { "100050": 1, "400090": "PrimaryCapability" } 

To remove an existing property, for example to remove the property for 400090, change the list to:

{ "100050": 1, "400090": "" }

Primary Key

A read-only value that indicates whether the attribute is a primary key for an index of this class in the database.

Hidden

An option that determines whether the attribute is hidden on the class form.

Allowable Currency Types

List of currency types allowed.

Currency

Attachment Pool

Name of the attachment pool to which the attachment field belongs.

Attachment Field

Default Value

The default attribute value that is saved for the attribute when you create a new instance and do not enter a value. Default Value can be a static value or a keyword from the field menu.

Enum Type

Specifies the way in which selection-field options are ordered in the database.

• Regular — BMC Remedy AR System assigns the IDs beginning with 0 and incrementing by 1.
• Custom — You must assign the IDs manually. You can enter any value from 10,001 through 214,74,83,647.
  Note: For out-of-the-box attributes, BMC has reserved a range of enum IDs from 0 to 10,000.

Selection

Functional Currency Types

List of currency types to which the value can be converted when it is saved to the database.

Currency

ID Values

If you selected a custom Enum Type for a selection field, enter the IDs for each of the values.

Note: For out-of-the-box attributes, BMC has reserved a range of enum IDs from 0 to 10,000. All new customizations must be done by using IDs starting from 10,001.

Selection

Input Length

Determines the maximum size of the attachment, measured in bytes. A value of 0 defaults to the maximum allowed by the database.

Attachment Field

List Format

If you want the attribute to contain a list of character values, enter the maximum number of elements in the list in the format L<max>. If you want the attribute to contain only one value, leave this field empty. For example, enter L4 to specify a maximum of four list elements. This maximum is enforced by the BMC Atrium CMDB API. When creating instances of this class, delimit list elements in this attribute with a semicolon (; ). To include a semicolon in a list element, place a backslash (\) in front of it. A semicolon after the last element is optional. For example, to create a list containing a, b, \;, and d, enter the string a;b;\;;d in this attribute when creating an instance of the class.

Character
