MABIS — Marktprozesse für Bilanzkreis- und Aggregationsverantwortliche

Process engine workflows for the German electricity balance group settlement processes. Implements PID 13003 (Bilanzkreisabrechnung Strom) from the BDEW MABIS specification (BNetzA BK6-24-174).

Process model (BKV perspective)

The BIKO (Bilanzkoordinator) is the central actor in MaBiS. It calculates and sends the Abrechnungssummenzeitreihe (billing summary time series) to each BKV (Bilanzkreisverantwortlicher). The BKV must respond with a Prüfmitteilung (positive or negative) within 1 Werktag (BK6-24-174 §13.8).

BIKO                               BKV (this crate)
────                               ────────────────
Abrechnungssummenzeitreihe ──────→ ReceiveSummenzeitreihe
                                       └─ register 1-WT deadline
                           ←──────── SendPruefmitteilungPositiv / Negativ (≤ 1 WT)
Datenstatus                ──────→ ReceiveDatastatus → Settled / Disputed

Key difference from supplier-switch workflows

Aspect	GPKE / WiM / GeLi Gas	MABIS (this crate)
Trigger	Single inbound EDIFACT	Abrechnungssummenzeitreihe from BIKO
Counterparty	NB / LFA	BIKO (Bilanzkoordinator)
Location scope	Single MeLo / MaLo	Billing period aggregate
Response Frist	24 h / 5 Wkt / 10 Wkt	1 Werktag (§13.8)
Outbound message	APERAK / CONTRL	Prüfmitteilung

PID Inventory

PID	Process name	Direction	Status
13003	Bilanzkreisabrechnung Strom (BIKO ↔ BKV)	inbound BIKO	✓ implemented

PIDs 13002–13028 are NOT MABIS. They are Messwerten-PIDs (MSCONS meter data exchange) in other domains. Never register 13002–13028 under "mabis-billing".

Usage

use mako_mabis::{MabisBillingWorkflow, BillingCommand, BillingVersion};
use mako_engine::{
    builder::EngineBuilder,
    event_store::InMemoryEventStore,
    types::{BikoId, BillingPeriod, BkvId, MessageRef, Pruefidentifikator},
};

let process = ctx.spawn::<MabisBillingWorkflow>(tenant_id, workflow_id);

// Step 1: BIKO sent Abrechnungssummenzeitreihe
process.execute(BillingCommand::ReceiveSummenzeitreihe {
    pid: Pruefidentifikator::new(13003).unwrap(),
    billing_period: BillingPeriod::new("2025-09"),
    bkv_id: BkvId::new("4033872000022"),
    biko_id: BikoId::new("10YDE-VE-TRANSMIX"),
    version: BillingVersion::Vorlaeufig,
    message_ref: MessageRef::new("MSCONS-BKA-2025-09-001"),
}).await?;

// Register 1-WT deadline (mabis-pruefmitteilung-1-werktag) in deadline store here.

// Step 2: BKV sends positive Prüfmitteilung
process.execute(BillingCommand::SendPruefmitteilungPositiv {
    message_ref: MessageRef::new("PRUEF-POS-2025-09-001"),
}).await?;

// Step 3: BIKO sends Datenstatus
process.execute(BillingCommand::ReceiveDatastatus {
    data_status: mako_mabis::DataStatus::AbgerechtneteDaten,
}).await?;
