In the UiPath REFramework, a Business Rule Exception signals a process-level issue that prevents successful processing of the transaction. It’s captured in the “Process Transaction” state. According to the REFramework documentation:

“Business Rule Exceptions are not retried because they are considered errors in the business logic or input data that need to be verified by a person (manual intervention).”

So, unlike System Exceptions (which can trigger retries), Business Rule Exceptions go to the “Set Transaction Status” state as “Failed”, and no retries are attempted for that transaction item.
