# Transmission of the monthly curtailed energy transfer time series (AAÜZ) — NB view The ANB delivers the curtailed energy transfer time series for the time period under consideration to the BIKO; the BIKO forwards the monthly AAÜZ to the BKV (of the LF). The BKV have received the aggregated AAÜZ and check them. The curtailed energy per TR is aggregated per market location and totaled across all market locations of the suppliers of the balancing group. ## Process flow from the perspective of the NB \nSystem diagram: Übermittlung der monatlichen Ausfallarbeitsüberführungszeitreihe (AAÜZ) — view of NB\n\n\nCustomer backend system\n\nMACO APP · NB\n\nMarket partner\n\n\n\n2.

**Flow**
  1. Message from **BIKO** · AS4
    **Response per decision tree** - `21002` → [E_0073](/en/referenz/202610/ebd/E_0073) · BIKO · Check AAÜZ
  2. **APERAK checks** - `21002` → `Z33`
  3. **Write endpoint** - Transaction created — [Create process data](/en/api/202610/backend-schreiben-nb/createprocessdata#prozessdaten-erstellen) `POST /createProcessData` Try it out Creates a new transaction in the backend with the data of the incoming message.

## Process information Wording of the consolidated version, profile ch. 17.3.3.3.1, pp. 257–258.
  1. ### Preconditions - Master data has been exchanged. - Curtailed energy has been determined by the grid operator per balancing group (right of first proposal).
  2. ### Results - In balancing terms, the BKV (of the LF) of the installation is placed as if the redispatch measure had not taken place. - The balancing group settlement for the BKV (of the LF) can be carried out. - The BKV (of the LF) checks the monthly AAÜZ.
  3. ### Further requirements The BIKO books the AAÜZ into the redispatch BK of the BKV (of the NB).
  4. ### First message **BIKO** sends “Response” (step 2). From here on, it is the turn of the party involved on this page.
  5. ### Objective The monthly AAÜZ determined by the grid operator is available to the BIKO and to 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/202610/NB--ANB/MaBiS-uebermittlung-der-monatlichen-ausfallarbeitsueberfuehrungszeitreihe-aauez) — connecting grid operator · market role NB - [View BIKO](/en/prozessdoku/202610/BIKO/MaBiS-uebermittlung-der-monatlichen-ausfallarbeitsueberfuehrungszeitreihe-aauez) — BIKO - [View BKV-LF](/en/prozessdoku/202610/BKV/MaBiS-uebermittlung-der-monatlichen-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.
