A calculated expression is a type of expression that includes a calculated field and a validation expression.

You can use the following functions to set a predefault or postdefault value in a business component. Siebel VB or COM objects do not support these functions:

• AccountId
• ContactLogin
• JobTitle
• OrganizationId

You cannot use a custom function in a calculated expression.

You can only use numbers between negative 2147483647 and 2147483648 in a field validation expression.
