Aware IM considers rules with a certain pattern to be validation rules. Here is an example of a validation rule:

IF Customer.Name IS UNDEFINED THEN REPORT ERROR 'Customer name is empty' 

Aware IM applies such rules when a user edits a business object on the object form and does not accept changes if the entered data is invalid. Also, Aware IM automatically generates validation rules to handle conditions the configurator may specify for object attributes such as required attributes or range of values.
