**Check identifiers** - [21005](/en/schnittstellen/202610/pruefi/IFTSTA/PI_21005) — Status message · AS4
**Flow**
  1. Message from **BKV (of the anfNB)** · AS4
    **Response per decision tree** - `21005` → [E_0099](/en/referenz/202610/ebd/E_0099) · BKV · Check monthly AAÜZ
  2. **Write endpoint** - Transaction created — `ERSTELLEN_PROZESSDATEN` Creates a new transaction in the backend with the data of the incoming message.
### Refusal of the validation notification AAÜZ
**Check identifiers** - [21004](/en/schnittstellen/202610/pruefi/IFTSTA/PI_21004) — Status message · AS4
**Flow**
  1. Message to **BKV (of the anfNB)** · AS4
    **Response per decision tree** - `21004` → [E_0081](/en/referenz/202610/ebd/E_0081) · BIKO · Check validation notification AAÜZ
  2. **Write endpoint** - Transaction updated — `AKTUALISIEREN_PROZESSDATEN` Updates the existing transaction in the backend once the message has been created.
### Forwarding of the validation notification AAÜZ
**Check identifiers** - [21003](/en/schnittstellen/202610/pruefi/IFTSTA/PI_21003) — Status message · AS4
**Flow**
  1. Message to **NB (ANB)** · AS4
    **Response per decision tree** - `21003` → [E_0099](/en/referenz/202610/ebd/E_0099) · BKV · Check monthly AAÜZ
  2. **Write endpoint** - Transaction updated — `AKTUALISIEREN_PROZESSDATEN` Updates the existing transaction in the backend once the message has been created.

## Process information
  1. ### First message **BKV (of the anfNB)** sends “Validation notification for monthly AAÜZ” (step 1). From this point on, the party on this page is next to act.
## Other views of the process The same process through the eyes of the other parties involved: the same steps, each read from their point of view. - [View ANB](/en/prozessdoku/202610/NB/MaBiS-uebermittlung-pruefmitteilung-fuer-die-ausfallarbeitsueberfuehrungszeitreihe-zwischen-den-bkv-anfnb-und-nb) — connecting grid operator · market role NB - [View BKV-ANFNB](/en/prozessdoku/202610/BKV/MaBiS-uebermittlung-pruefmitteilung-fuer-die-ausfallarbeitsueberfuehrungszeitreihe-zwischen-den-bkv-anfnb-und-nb) — balance responsible party of the requesting grid operator · market role BKV *The source provides no use case profile for this process — objective, precondition and result are not recorded there.* *The steps are the **possible** messages of this process, not a sequence — the source lists neither conditions nor alternatives. The small box on the step names the own view on the left: with **←** it receives, with **→** it sends. Collapsed steps run between other market partners.* The connector table lists no write call for these steps. Derived from the process flow: the process begins for the own role with their message, so the transaction is created. Applies to: [1](#schritt-1) For this market role there is no write catalog; the step therefore shows only the command of the write call, without address and without button. Applies to: [1](#schritt-1), [2](#schritt-2), [3](#schritt-3)
