ABusiness Exceptiondescribes an error rooted in the fact that certain data which the automation project depends on is incomplete or missing.

Retrying the transaction does not yield any chance of solving the issue, and there are other better courses of action, such as notifying the human user of this error.

By default, Orchestrator doesnotretry transactions which are failed due toBusiness Exceptions. This happens because an inconsistency between the transaction value and the business requirement means that there might be errors in the initial data which the queue items were created from. Additional actions by human users might be required to fix this type of issue, and logging this type of exception and notifying the responsible person can be useful.
