Open Form
An attribute rule is a specification of a business rule. There are two types of attribute rules:
•checks on validity: attribute rules that impose requirements on data to approve them. Examples are ‘the amount of the invoice line must be different than 0’ or ‘the user being the task owner must have checked the task owner flag’.
•actions: actions are pieces of programs being executed under special conditions.
Actions can be classified in two sorts of actions:
•actions being executed before a changed piece of data is stored, for example, when entering the default or constant values in fields.
•actions being executed after a changed piece of data is stored, for example, when sending an email.
The registration of attribute rules is a typical activity for application developers. See the warning under Application Development.
