When you are required to retry the execution of the sequence before an exception occurs,
the Rethrow activity can be used. Rethrow activity throws a previously thrown exception
from within a TryCatch activity while retaining the original source of the exception.

.

Example

1.      Let’s continue from Try Catch activity,

2.      Add Rethrow activity to the catch block below the sequence.

3.      Add another Try Catch and place the before TryCatch activity inside the Try block.

4.      Now, execute the workflow if there is an exception it rethrows and handles the exception.
