# Activation of a MaBiS metering point for the balancing group aggregated time series from the NB to BIKO and BKV — BIKO view The NB activates the MaBiS-ZP of a BK-SZR (category A) and sends the corresponding information to the BIKO, which the BIKO accepts or rejects. Once received, the BIKO forwards the activation of a MaBiS-ZP for a BK-SZR (category A) to the BKV, provided the activation was correct. The BKV can inform the NB about an activation it considers faulty. In the event of an error message from the BKV, the NB and the BKV clarify where the error lies and – if necessary – ensure that the error is corrected. ## Process flow from the perspective of the BIKO \nSystem diagram: Aktivierung eines MaBiS-Zählpunkts für die Bilanzkreissummenzeitreihe vom NB an BIKO und BKV — view of BIKO\n\n\nCustomer backend system\n\nMACO APP · BIKO\n\nMarket partner\n\n\n\n1.

**Check identifiers** - [55062](/en/schnittstellen/202604/pruefi/UTILMD/PI_55062) — Activation of ZP · AS4
**Flow**
  1. Message from **NB** · AS4
  2. **Write endpoint** - Transaction created — `ERSTELLEN_PROZESSDATEN` Creates a new transaction in the backend with the data of the incoming message.
### Response
**Check identifiers** - [55064](/en/schnittstellen/202604/pruefi/UTILMD/PI_55064) — Response · AS4
**Flow**
  1. Message to **NB** · AS4
    **Response per decision tree** - `55064` → [E_0034](/en/referenz/202604/ebd/E_0034) · BIKO · Check MaBiS-ZP activation
  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. 10.4.1, pp. 123–124.
  1. ### Preconditions - The NB assigns the first market location with NB aggregation responsibility to a combination of BK, ZRT and BG for which no MaBiS-ZP for the BK-SZR (category A) is activated yet.
  2. ### Results - The BIKO and the BKV can assign the BK-SZR (category A) to a MaBiS-ZP.
  3. ### First message **NB** sends “Activation of a MaBiS-ZP for the BK-SZR (category A)” (step 1). From here on, the party involved on this page has the next move.
  4. ### Objective - The NB has activated the MaBiS-ZP for the corresponding BK-SZR (category A) at the BIKO. - The BIKO has forwarded the MaBiS-ZP for the BK-SZR (category A) to the BKV, and the BKV has accepted it and, in the error case, initiated clearing with the NB where applicable.
## 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 NB](/en/prozessdoku/202604/NB/MaBiS-aktivierung-eines-mabis-zaehlpunkts-fuer-die-bilanzkreissummenzeitreihe-vom-nb-an-biko-und-bkv) — NB - [View BKV](/en/prozessdoku/202604/BKV/MaBiS-aktivierung-eines-mabis-zaehlpunkts-fuer-die-bilanzkreissummenzeitreihe-vom-nb-an-biko-und-bkv) — 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 numbers are those of the source; where one is missing, it is missing there.* 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), [4](#schritt-4)
