# Transmission of data status for the monthly curtailed energy transfer time series (AAÜZ) — BKV-LF view The BIKO transmits the data status to the NB and the BKV (of the LF) for the AAÜZ - after receipt of the AAÜZ from the NB or - after receipt of the validation notification from the BKV (of the LF) or - after use of the AAÜZ for the BKA (without KBKA) or the KBKA. ## Process flow from the perspective of the BKV (BKV-LF) \nSystem diagram: Übermittlung Datenstatus für die monatliche Ausfallarbeitsüberführungszeitreihe (AAÜZ) — view of BKV\n\n\nCustomer backend system\n\nMACO APP · BKV (des LF)\n\nMarket partner\n\n\n\n1.

**Check identifiers** - [21004](/en/schnittstellen/202610/pruefi/IFTSTA/PI_21004) — Status message · AS4
**Flow**
  1. Message from **BIKO** · AS4
    **Response per decision tree** - `21004` → [E_0075](/en/referenz/202610/ebd/E_0075) · BIKO · Assign data status AAÜZ after completed BKA - `21004` → [E_0076](/en/referenz/202610/ebd/E_0076) · BIKO · Assign data status after receipt of a AAÜZ - `21004` → [E_0077](/en/referenz/202610/ebd/E_0077) · BIKO · Assign data status once a validation notification for the AAÜZ is available
  2. **Write endpoint** - Transaction created — `ERSTELLEN_PROZESSDATEN` Creates a new transaction in the backend with the data of the incoming message.
### Data status for the monthly AAÜZ This step runs between other market partners and is not relevant for this view.

## Process information Wording of the consolidated version, profile ch. 17.3.3.5.1, pp. 262–263.
  1. ### Results All systems of BKV, BIKO and NB hold the same data status for a version of the AAÜZ.
  2. ### Error case #### Result in the error case The BIKO informs all affected market participants and, after the error has been corrected, ensures that the correct data status is assigned to all affected AAÜZ. #### Error cases The algorithm applied by the BIKO for assigning the data status is faulty.
  3. ### Further requirements The BKV (of the LF) is contacted by the NB to clarify the errors. The BKV (of the LF) can also contact the NB.
  4. ### First message **BIKO** sends “Data status for the monthly AAÜZ” (step 1). From here on, it is the turn of the party involved on this page.
  5. ### Objective The data status managed by the BIKO is available at the NB, at the BKV (of the LF) for the AAÜZ.
## 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-datenstatus-fuer-die-monatliche-ausfallarbeitsueberfuehrungszeitreihe-aauez) — connecting grid operator · market role NB - [View BIKO](/en/prozessdoku/202610/BIKO/MaBiS-uebermittlung-datenstatus-fuer-die-monatliche-ausfallarbeitsueberfuehrungszeitreihe-aauez) — BIKO *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)
