This is the heart of the exception definition. Depending on the complexity of the exception definition, you can use Simple or Advanced conditions to model the exception condition.

Simple Condition
When defining an exception condition, verify that when the condition is true it results in an exception. Select whether to generate the exception when all the conditions are met, or when any of the conditions are met. Define the exception using the following criteria:
• Attribute
• Operator
• Value (from)
• Value (to)

While defining simple condition, you can also specify for this exception whether you want all the conditions required, or any of the conditions required. This is accomplished by selecting one of the following options:
• When all of the conditions are met
• When any of the conditions are met

Important: If there is no list of values available for a particular attribute used for the custom exception, the system shows a warning message. In such case, you should ignore this warning message and continue defining the condition.

Advanced Condition
If the Simple Condition window does not meet your exception definition, use the Advanced Condition definition window. In this window you use SQL to define conditions. In advanced condition, you can define conditions using attributes from three views such as Company, Customer, and Supplier.
