**Check identifiers** - [21005](/en/schnittstellen/202604/pruefi/IFTSTA/PI_21005) — Status message · AS4
**Flow**
  1. Message from **BKV (of the LF)** · AS4
    **Response per decision tree** - `21005` → [E_0098](/en/referenz/202604/ebd/E_0098) · 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 monthly AAÜZ
**Check identifiers** - [21004](/en/schnittstellen/202604/pruefi/IFTSTA/PI_21004) — Status message · AS4
**Flow**
  1. Message to **BKV (of the LF)** · AS4
    **Response per decision tree** - `21004` → [E_0074](/en/referenz/202604/ebd/E_0074) · 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 monthly AAÜZ
**Check identifiers** - [21003](/en/schnittstellen/202604/pruefi/IFTSTA/PI_21003) — Status message · AS4
**Flow**
  1. Message to **NB (ANB)** · AS4
    **Response per decision tree** - `21003` → [E_0098](/en/referenz/202604/ebd/E_0098) · 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 Wording of the consolidated version, profile ch. 17.3.3.4.1, p. 260.
  1. ### Preconditions - The BKV (of the LF) has received a version of the AAÜZ. - The BKV (of the LF) has received the data basis from the supplier.
  2. ### Results - On receipt of a negative validation notification, the NB transmits a corrected AAÜZ where applicable. - The BIKO can form the data status and transmit it to the BKV (of the LF) and NB.
  3. ### First message **BKV (of the LF)** sends “Validation notification for monthly AAÜZ” (step 1). From this point on, the party on this page is next to act.
  4. ### Objective The NB knows the expectation (need for correction or acceptance) of the BKV (of the LF) for the AAÜZ of the time period under consideration. With the exchange of the validation notification, all market participants involved learn the check result of the BKV (of the LF).
## 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/202604/NB/MaBiS-uebermittlung-pruefmitteilung-fuer-die-monatliche-ausfallarbeitsueberfuehrungszeitreihe-aauez) — connecting grid operator · market role NB - [View BKV-LF](/en/prozessdoku/202604/BKV/MaBiS-uebermittlung-pruefmitteilung-fuer-die-monatliche-ausfallarbeitsueberfuehrungszeitreihe-aauez) — balance responsible party of the supplier · market role BKV *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.
