# Transmission of the settlement aggregated time series for balancing group settlement from BIKO to NB — NB view The BIKO determines a preliminary NB-DZR of a BG within the BKA, assigns it to the BK named by the NB and transmits it to the NB. After the BKA has expired, the BIKO determines the final NB-DZR of a BG, assigns it to the BK named by the NB and transmits it to the NB. ## Process flow from the perspective of the NB \nSystem diagram: Übermittlung der Abrechnungssummenzeitreihe für Bilanzkreisabrechnung vom BIKO an NB — view of NB\n\n\nCustomer backend system\n\nMACO APP · NB\n\nMarket partner\n\n\n\n1.

**Flow**
  1. Message from **BIKO** · AS4
  2. **Load data for the incoming check** - [Read market location](/en/api/202610/backend-lesen/getmarketlocationbasic#marktlokation-lesen) `GET /getMarketLocationBasic` Try it - [Read meter](/en/api/202610/backend-lesen/getcounterbasic#zahler-lesen) `GET /getCounterBasic` Try it
  3. **Write endpoint** - Transaction created — [Create process data](/en/api/202610/backend-schreiben-nb/createprocessdata#prozessdaten-erstellen) `POST /createProcessData` Try it out Creates a new transaction in the backend with the data of the incoming message.
## Process information Wording of the consolidated version, profile ch. 13.9.1, pp. 196–197.
  1. ### Preconditions - The NB has named a BK for its BG to which the NB-DZR is assigned. - The MaBiS-ZP for the NB-DZR was activated by the BIKO at the NB. - The BIKO has determined the NB-DZR.
  2. ### Results The NB starts analysing the causes of the energy allocation as early as the transmission of the preliminary NB-DZR for the BKA and initiates the clearing with the market partners.
  3. ### First message **BIKO** sends “Transmission NB-DZR” (step 1). From here on, it is the turn of the party involved on this page.
  4. ### Objective The settlement aggregated time series has been transmitted by the BIKO to the NB.
## 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-uebermittlung-der-abrechnungssummenzeitreihe-fuer-bilanzkreisabrechnung-vom-biko-an-nb) — BIKO *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 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 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.
