The AcceptorReconciliationResponse message is sent by the acquirer (or its agent) to an acceptor (or its agent), to ensure that the debits and credits performed by the acceptor matches the computed balances of the acquirer for the debits and credits performed during the same reconciliation period. If the acceptor or the acquirer notices a difference in totals, the discrepancy will be resolved by other means, outside the scope of the protocol.
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 AcceptorReconciliationResponseV02 implementation follows a specific implementaiton pattern. First of all, AcceptorReconciliationResponseV02 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, AcceptorReconciliationResponseV02Document implements IOuterDocument. Because AcceptorReconciliationResponseV02 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type AcceptorReconciliationResponseV02.
classDiagram
class IOuterRecord
AcceptorReconciliationResponseV02 --|> IOuterRecord : Implements
AcceptorReconciliationResponseV02Document --|> IOuterDocument~AcceptorReconciliationResponseV02~ : Implements
class IOuterDocument~AcceptorReconciliationResponseV02~ {
AcceptorReconciliationResponseV02 Message
}
Document wrapper for serialization
The only real purpose AcceptorReconciliationResponseV02Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:caaa.010.001.02’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using AcceptorReconciliationResponseV02.ToDocument() method. The returned AcceptorReconciliationResponseV02Document value will serialize correctly according to ISO 20022 standards.
