# Activation of a MaBiS-ZP for the monthly curtailed energy transfer time series (AAÜZ) between NB and BKV (anfNB) — ANB view The ANB activates a MaBiS-ZP of a AAÜZ and sends the corresponding information to the BIKO, which is accepted or rejected by the BIKO. On receipt, the BIKO forwards the activation of a MaBiS-ZP for a AAÜZ to the BKV (of the anfNB), provided the activation was correct. The BKV (of the anfNB) can inform the ANB of an activation that it considers faulty. In the event of an error message from the BKV, ANB and BKV (of the anfNB) clarify where the error lies and – if necessary – arrange for the error to be corrected. ## Process flow from the perspective of the NB (ANB) \nSystem diagram: Aktivierung eines MaBiS-ZP für die monatliche Ausfallarbeitsüberführungszeitreihe (AAÜZ) zwischen NB und BKV (anfNB) — view of NB\n\n\nCustomer backend system\n\nMACO APP · NB (ANB)\n\nMarket partner\n\n\n\n1.

## Process information Wording of the consolidated version, profile ch. 17.3.5.1.1, pp. 267–268.
  1. ### Preconditions The ANB has possible redispatch measures in the grid area for which it is not the requesting NB and for which no MaBiS-ZP for the AAÜZ is activated yet at the requesting NB.
  2. ### Results The BIKO can assign the AAÜZ to the MaBiS-ZP.
  3. ### Error case #### Result in the error case The BIKO and the BKV (of the anfNB) can assign the AAÜZ to a Ma-BiS-ZP. In the error case, the BKV (of the anfNB) can initiate the clearing process with the ANB.
  4. ### First message The party involved on this page sends this itself: “Activation of a MABIS-ZP for the monthly AAÜZ” to **BIKO** (step 1).
  5. ### Objective - The NB has activated the MaBiS-ZP for the corresponding AAÜZ at the BIKO. - The BIKO has forwarded the MaBiS-ZP for the AAÜZ 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-zp-fuer-die-monatliche-ausfallarbeitsueberfuehrungszeitreihe-aauez-zwischen-nb-und-bkv-anfnb) — BIKO - [View BKV-ANFNB](/en/prozessdoku/202610/BKV/MaBiS-aktivierung-eines-mabis-zp-fuer-die-monatliche-ausfallarbeitsueberfuehrungszeitreihe-aauez-zwischen-nb-und-bkv-anfnb) — balance responsible party of the requesting grid operator · market role 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)
