# Activation of a MaBiS metering point for the balancing area aggregate time series from the ÜNB to BIKO and NB — NB view The ÜNB activates a MaBiS-ZP of a BG-SZR (category B) and sends the corresponding information to the BIKO, which is accepted or rejected by the BIKO. On receipt, the BIKO forwards the activation of the MaBiS-ZP for a BG-SZR (category B) to the NB, provided the activation was correct. The NB can inform the ÜNB of an activation that it considers faulty. In the event of an error message from the NB, ÜNB and NB clarify where the error lies and – if necessary – arrange for the error to be corrected. ## Process flow from the perspective of the NB \nSystem diagram: Aktivierung eines MaBiS-Zählpunkts für die Bilanzierungsgebietssummenzeitreihe vom ÜNB an BIKO und NB — view of NB\n\n\nCustomer backend system\n\nMACO APP · NB\n\nMarket partner\n\n\n\n4.

## Process information Wording of the consolidated version, profile ch. 9.2.1, pp. 100–101.
  1. ### Preconditions The ÜNB has been informed by the NB responsible for the BG about the assignment of the first market location with ÜNB aggregation responsibility, for whose assigned combination of ZRT, voltage level and BG no MaBiS-ZP for the BG-SZR (category B) is activated yet.
  2. ### Results - The BIKO and the NB can assign the BG-SZR (category B) to a MaBiS-ZP.
  3. ### First message **BIKO** sends “Forwarding of the activated MaBiS-ZP for the BG-SZR (category B)” (step 4). From here on, it is the turn of the party involved on this page.
  4. ### Objective - The ÜNB has activated the MaBiS-ZP for the corresponding BG-SZR (category B) at the BIKO. - The BIKO has forwarded the MaBiS-ZP for the BG-SZR (category B) to the NB, and the NB has accepted it and, in the error case, initiated clearing with the ÜNB 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 BIKO](/en/prozessdoku/202610/BIKO/MaBiS-aktivierung-eines-mabis-zaehlpunkts-fuer-die-bilanzierungsgebietssummenzeitreihe-vom-uenb-an-biko-und-nb) — BIKO - [View ÜNB](/en/prozessdoku/202610/UENB/MaBiS-aktivierung-eines-mabis-zaehlpunkts-fuer-die-bilanzierungsgebietssummenzeitreihe-vom-uenb-an-biko-und-nb) — ÜNB · market role UENB *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.
