Struct ErpEvent 

pub struct ErpEvent {
    pub idempotency_key: String,
    pub event_type: ErpEventType,
    pub process_id: ProcessId,
    pub tenant_id: TenantId,
    pub conversation_id: ConversationId,
    pub causation_id: EventId,
    pub pid: u32,
    pub payload_schema: Option<String>,
    pub payload: Value,
    pub occurred_at: OffsetDateTime,
}

A structured process event delivered from mako-engine to the ERP.

The payload is always a BO4E-typed JSON object — the ERP adapter never receives raw EDIFACT bytes or EDIFACT format-version identifiers.

On the wire (via WebhookErpAdapter) this struct is serialised as a CloudEvents 1.0 structured-mode JSON envelope with Content-Type: application/cloudevents+json. The BO4E payload lives in the CloudEvents data field; payload_schema maps to dataschema; event_type maps to the type attribute via ErpEventType::cloud_event_type.

Idempotency

idempotency_key maps to the CloudEvents id attribute and is also sent as X-Idempotency-Key for ERP middleware that keys on headers. The ERP must persist this key and return HTTP 200 OK for duplicate deliveries.

Fields

idempotency_key: String

Stable dedup key — store in the ERP to reject duplicate deliveries.

Derived from the outbox message_id; stable across retries.

event_type: ErpEventType

Semantic classification of this event.

process_id: ProcessId

The mako process that generated this event.

tenant_id: TenantId

Tenant (operator GLN) that owns this process.

conversation_id: ConversationId

BDEW business conversation identifier.

causation_id: EventId

The mako domain event that directly caused this ERP notification.

pid: u32

Prüfidentifikator of the process.

payload_schema: Option<String>

BO4E JSON Schema URL that validates payload.

Examples:

• "https://raw.githubusercontent.com/BO4E/BO4E-Schemas/v202501.0.0/src/bo4e_schemas/bo/Marktlokation.json"
• "https://raw.githubusercontent.com/BO4E/BO4E-Schemas/v202501.0.0/src/bo4e_schemas/bo/Messlokation.json"

None for events where no primary BO4E object is applicable (e.g. ContrlReceived).

payload: Value

BO4E-typed payload.

Deserialise using the ERP’s own BO4E library. Raw EDIFACT structures are never exposed here. null when no payload is applicable.

occurred_at: OffsetDateTime

Wall-clock time when the domain event was persisted.
