In particular, the following notifications may be returned to the sender:

[nrumohammadx1]

Message sender : this may be the Customer or the Supplier from which the Message originates;
Message recipient : this may be the Customer or Supplier to whom the Message is addressed;
Sender : which may be the Customer, the Supplier or the Intermediary who sends the Message to NSO;
Recipient : which can be the Customer, the Supplier or the Intermediary who receives the Message from NSO.
From this we can deduce the importance of the intermediary , because, as happens in the SdI-Electronic Invoicing model, this actor becomes the main manager, organizational and technological, of the electronic order , allowing the integration of this document with the management and accounting systems of customers and suppliers and, downstream, the digital conservation in compliance with the law, which is necessary as these are electronic documents.



NSO Functions
NSO performs three main functions, on behalf of the Central State Administration and towards its suppliers:

Identification , with which NSO provides for the unique identification bahamas phone data of messages in transit that contain the “electronic order” document;
Validation , with which NSO verifies the correctness of the data that make up the Message;
Transmission, with which NSO forwards the Message to the Recipient (Customer, Supplier or Intermediary), if validated.
As also indicated in the following paragraph, these functions are activated on the basis of the chosen transmission channel. For each of these functions and for each transmitted object, different sets of controls are activated that generate specific notifications , also consisting of messages in structured formats, in order to allow their automated management on the internal management or accounting systems.


For the validation function :

rejection/non-validation;
For the transmission function :

failure to deliver;
transmission occurred with impossibility of delivery.
