An invariant of Anlage 6 / the AWH „Zum Modell 2“ that the caller’s data breaks.

Every variant names the clause it enforces. None of them is a wire error: this crate does no I/O, so all of these are statements about the operator’s own records.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotFirstOfMonth

A Bilanzierungsgebiet may begin, change or end only on the first of a month (AWH Kap. 5.3.1.3: „Die Bildung und Änderung von einem BG erfolgt nur zum Ersten eines Monats“).

Fields

was: &'static str

Which lifecycle instant was wrong.

date: Date

The date the caller supplied.

DoppeltesBilanzierungsgebiet

A Ladepunktbetreiber holds at most one Bilanzierungsgebiet per Regelzone (AWH Kap. 5.3).

Fields

regelzone: String

The Regelzone that already has one.

AnmeldungVorBgBeginn

The Übergabestelle’s Anmeldedatum precedes the BG’s Gültigkeitsbeginn (AWH Kap. 2.1.2 Nr. 1: „Das Anmeldedatum darf nicht vor dem Gültigkeitsbeginn des BG liegen“).

Fields

anmeldung: Date

The requested Anmeldedatum.

bg_start: Date

The BG’s Gültigkeitsbeginn.

AnmeldungNachBgEnde

The Anmeldedatum falls on or after the day the BG stops being valid.

The AWH states only the lower bound, because a BG that has been beendet is not a BG one can register against at all: a Marktlokation balanced into an expired Bilanzierungsgebiet has no Bilanzkreis- Zuordnung on the day it takes effect, and the BIKO has nothing to settle it against (AWH Kap. 5.3.1.3, Anlage 6 §II).

Fields

anmeldung: Date

The requested Anmeldedatum.

bg_ende: Date

The first day the BG is no longer valid.

EegAnlageAusserhalbDesBeschlusses

A Kundenanlage carrying an EEG-geförderte Anlage was onboarded on the BK6-24-267 path.

The Beschluss is explicit that its scope excludes „Kundenanlagen mit EEG-geförderten Anlagen oder anderweitig komplexen Strukturen“ (S. 28). It does not decide the case either way, so the model cannot be applied to it without a bilateral agreement — and applying it anyway would balance an EEG-vergütete Einspeisung into the LPB’s BG.

KeineViertelstundenmessung

The Übergabestelle is not quarter-hour metered.

Anlage 6 §III.1 makes ¼-h measurement — a Zählerstandsgang or registrierende Leistungsmessung — a precondition of the model. Without it there is nothing to allocate against.

ErhaltungVerletzt

The conservation identity of Anlage 6 §IV.1 does not hold.

Raised only where it is a bug — a caller that assembled a version by hand and got the arithmetic wrong. The ordinary shortfall is not this: it is the Deltamenge, which is a quantity with a Bilanzkreis of its own.

Fields

slot: String

The quarter hour, as an RFC 3339 instant.

ngz: Decimal

The Netzgangzeitreihe value.

summe: Decimal

What the parts add up to.

delta: Decimal

The Deltamenge that was recorded.

VersionIstFinal

A version already sealed as Final was edited.

MaBiS Kap. 3.8.2 versions by Erstellungszeitpunkt; once a version has settled it is immutable and a correction is a new version.

Fields

erstellungszeitpunkt: String

The sealed version’s Erstellungszeitpunkt.

KorrekturfristAbgelaufen

A correction arrived after the MaBiS Korrekturfrist.

MaBiS Kap. 3.10 closes the window at the end of month M+7 relative to the Bilanzierungsmonat.

Fields

monat: String

The Bilanzierungsmonat, as YYYY-MM.

frist: Date

The last day corrections were accepted.

eingang: Date

When the correction arrived.

DoppelterAnspruch

Two claims in one quarter hour name the same virtual Marktlokation.

Refused rather than summed. A MaLo appearing twice produces two crate::allocation::Zuordnung rows for one Bilanzkreis-Zuordnung, and every downstream consumer that keys by MaLo — the BK-SZR aggregation above all — silently keeps one of them. Merge the claims upstream, where the reason they are two is still known.

Fields

malo: String

The Marktlokation that appears more than once.

LadevorgangZuLang

A Ladevorgang spans more quarter hours than a session can.

Not a regulatory bound but a corruption guard: the split walks one slot at a time, so an ende that a backend got wrong by a factor of a thousand would otherwise allocate until the process dies. A year of quarter hours is already three orders of magnitude past the longest real charging session.

Fields

id: String

The session’s own id.

slots: u64

How many quarter hours it would span.

max: u64

The most a session may span.

Allocation(String)

The allocation could not be formed at all.
