This occurs when the mailman changes the reception gap e-invoice?
Short answer
The outage does not occur automatically, but may arise if the deregistration of the old route, registration of a new provider, SMP recording or test of document skills is poorly timed. In good practice, the same participant's identifier should still be visible to partners, only directed to the new provider. It is critical to test the look and real acceptance before the end of the old process.
Export and Plan
Download archive, accesses, developed states and prepare rollback.
MP direction
See if the participant ID is directed to the new provider.
Income test
Verify the actual invoice received, not just a successful login.
First days
Check undelivered documents, notifications and error queues.
Conclusion
The failure to change mail is a controlled risk. It shall be minimised by the correct timing of the SMP change, acceptance test, monitoring and return plan.
