The SaleToPOIEventNotification message is sent by a POI or a sale terminal to inform the other about the happening of an event.
Message Construction
Every ISO20022 message has at the highest level what we call ‘building blocks’. Because the message is constructed as immutable records, the association is by composition. Below you can see the relationship between the message and its constituent building blocks: For comparison, see the ISO20022 official specification

Extensibility and generalization considerations
To facilitate generalized design patterns in the system, the SaleToPOIEventNotificationV02 implementation follows a specific implementaiton pattern. First of all, SaleToPOIEventNotificationV02 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, SaleToPOIEventNotificationV02Document implements IOuterDocument. Because SaleToPOIEventNotificationV02 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type SaleToPOIEventNotificationV02.

class IOuterRecord
SaleToPOIEventNotificationV02 --|> IOuterRecord : Implements
SaleToPOIEventNotificationV02Document --|> IOuterDocument~SaleToPOIEventNotificationV02~ : Implements
class IOuterDocument~SaleToPOIEventNotificationV02~ {
SaleToPOIEventNotificationV02 Message
}
Document wrapper for serialization
The only real purpose SaleToPOIEventNotificationV02Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:casp.012.001.02’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using SaleToPOIEventNotificationV02.ToDocument() method. The returned SaleToPOIEventNotificationV02Document value will serialize correctly according to ISO 20022 standards.
