# Deactivation of a MaBiS metering point for the balancing group aggregated time series from the NB to the BIKO and the BKV — NB view The NB deactivates the activated MaBiS-ZP for 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 deactivation of a MaBiS-ZP for a BK-SZR (category A) to the BKV, provided it has accepted the deactivation. The BKV can inform the NB about a deactivation 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: Deaktivierung 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. 10.5.1, pp. 126–127.
  1. ### Preconditions - The NB ends the assignment of the last market location with NB aggregation responsibility, and for whose assigned combination of BK, ZRT and BG a MaBiS-ZP for the BK-SZR (category A) is activated, and this MaBiS-ZP is activated at the BIKO.
  2. ### Further requirements After the point in time of deactivation, the MaBiS-ZP can no longer be used until it is activated again for the BK-SZR (category A).
  3. ### First message The party involved on this page is itself the sender of: „Deactivation of a MaBiS-ZP for the BK-SZR (category A)“ to **BIKO** (step 1).
  4. ### Objective - The NB has deactivated the MaBiS-ZP for the BK-SZR (category A) at the BIKO. - The BIKO has forwarded the deactivation of 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-deaktivierung-eines-mabis-zaehlpunkts-fuer-die-bilanzkreissummenzeitreihe-vom-nb-an-biko-und-bkv) — BIKO - [View BKV](/en/prozessdoku/202610/BKV/MaBiS-deaktivierung-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)
