# Activation of a MaBiS metering point for the balancing group aggregated time series from the NB to BIKO and BKV — NB 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 NB \nSystem diagram: Aktivierung eines MaBiS-Zählpunkts für die Bilanzkreissummenzeitreihe vom NB an BIKO und BKV — view of NB\n\n\nCustomer backend system\n\nMACO APP · NB\n\nMarket partner\n\n\n\n1.

## 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 The party involved on this page sends this itself: “Activation of a MaBiS-ZP for the BK-SZR (category A)” to **BIKO** (step 1).
  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 BIKO](/en/prozessdoku/202610/BIKO/MaBiS-aktivierung-eines-mabis-zaehlpunkts-fuer-die-bilanzkreissummenzeitreihe-vom-nb-an-biko-und-bkv) — BIKO - [View BKV](/en/prozessdoku/202610/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 source does not yet name the event that triggers these steps. Applies to: [1](#schritt-1) The connector table lists no write call for these steps. Derived from the process flow: the own role was already involved in this process, so the transaction already exists. Applies to: [2](#schritt-2) For the check identifiers of these steps there is no test case in the test data set; the »Try it out« button of the write interface therefore offers no body. Applies to: [1](#schritt-1), [2](#schritt-2)
