Rethrow

You can use this activity to re-raise or rethrow an exception that was caught earlier in the workflow.

When the Rethrow activity is run within a Catch block, the exception caught earlier is rethrown. However, if the Rethrow activity has an outer Try-Catch block, there is a possibility that the exception is caught by the Try-Catch block. If not, the workflow stops and the error is reported.

See, RPA flow to use the Throw and Rethrow activities example.
