The limit can be infinite, since if there is an incident for any reason in saving the documents of a specific request, there is no known date when the documentation associated with a settlement can be recovered. Our recommendation is to establish a retry policy, which is finite, but which can be restarted at a given time.

Why? There is a possibility that the source application was unable to load the documentation, and therefore, the documents may be recoverable (if the incident in the source application in question can be resolved).
