The Error message is sent by any party to any party (acquirer, agent or issuer) to indicate a message error.
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 ErrorV03 implementation follows a specific implementaiton pattern. First of all, ErrorV03 impleemnts IOuterRecord indicating it is the outermost logical part of the message definition. Like all message wrappers, ErrorV03Document implements IOuterDocument. Because ErrorV03 implements IOuterDocument, it is a suitable template parameter for IOuterDocument, and causes the internal ‘Message’ to be of type ErrorV03.
classDiagram class IOuterRecord ErrorV03 --|> IOuterRecord : Implements ErrorV03Document --|> IOuterDocument~ErrorV03~ : Implements class IOuterDocument~ErrorV03~ { ErrorV03 Message }
Document wrapper for serialization
The only real purpose ErrorV03Document serves is to cause the document to be serialized into the ‘urn:iso:std:iso:20022:tech:xsd:caad.007.001.03’ namespace. Therefore, it will probably be the usual practice to build the message and construct this wrapper at the last minute using ErrorV03.ToDocument() method. The returned ErrorV03Document value will serialize correctly according to ISO 20022 standards.
