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

Now, we will zero-in one-by-one on each of these building blocks.
Header building block

Extensibility and generalization considerations
To facilitate generalized design patterns in the system, the SaleToPOIEventNotificationV05 implementation follows a specific implementaiton pattern. First of all, SaleToPOIEventNotificationV05 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, SaleToPOIEventNotificationV05Document implements IOuterDocument. Because SaleToPOIEventNotificationV05 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type SaleToPOIEventNotificationV05.

class IOuterRecord
SaleToPOIEventNotificationV05 --|> IOuterRecord : Implements
SaleToPOIEventNotificationV05Document --|> IOuterDocument~SaleToPOIEventNotificationV05~ : Implements
class IOuterDocument~SaleToPOIEventNotificationV05~ {
SaleToPOIEventNotificationV05 Message
}
Document wrapper for serialization
The only real purpose SaleToPOIEventNotificationV05Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:casp.012.001.05’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using SaleToPOIEventNotificationV05.ToDocument() method. The returned SaleToPOIEventNotificationV05Document value will serialize correctly according to ISO 20022 standards.
