Oracle Exam 1z0-493 Topic 1 Question 2 Discussion

You have a process with two automated tasks that execute in the following sequence: the first task reserves in an inventory system and the second task activates the resources in an activation system. Because you know that the inventory system may return resources that are already in use, you expect to eventually receive some errors from the activation system.

What would be the best way to use an amendment to force the re-execution of resource reservation when you receive these errors during the execution of the second task?
