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

**Check identifiers** - [13003](/en/schnittstellen/202604/pruefi/MSCONS/PI_13003) — Aggregated time series · AS4
**Flow**
  1. Message from **BIKO** · AS4
  2. **Write endpoint** - Transaction created — `ERSTELLEN_PROZESSDATEN` Creates a new transaction in the backend with the data of the incoming message.
## Process information Wording of the consolidated version, profile ch. 13.10.1, p. 199.
  1. ### Preconditions - The ÜNB has named a BK to which the ÜNB-DZR is assigned. - The MaBiS-ZP for the ÜNB-DZR was activated by the BIKO at the ÜNB. - The BIKO has determined the ÜNB-DZR.
  2. ### Results The ÜNB begins analysing the causes of the energy allocation as early as the transmission of the preliminary ÜNB-DZR for the BKA and initiates the clearing with the market partners.
  3. ### First message **BIKO** sends “Transmission ÜNB-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 ÜNB.
## 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/202604/BIKO/MaBiS-uebermittlung-der-abrechnungssummenzeitreihe-fuer-bilanzkreisabrechnung-vom-biko-an-uenb) — 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 this market role there is no write catalog; the step therefore shows only the command of the write call, without address and without button. Applies to: [1](#schritt-1)
