A Business Exception is an exception that occurs due to an incorrect or incomplete input data or an expected business rule violation.

A Business Exception can be thrown by using the Throw activity in UiPath Studio, with the exception type set to UiPath.Core.BusinessRuleException. Alternatively, a Business Exception can be thrown by using the Set Transaction Status activity in the REFramework, with the status set to Failed and the exception type set to Business Exception. References: [Business Exception vs Application Exception], [Throw], [Set Transaction Status]
