# Transmission of the balancing area aggregate time series from ÜNB — NB view The ÜNB delivers the BG-SZR (category B) for the time period under consideration to the BIKO. The BIKO forwards the BG-SZR (category B) to the NB, provided it is not to be rejected. ## Process flow from the perspective of the NB \nSystem diagram: Übermittlung der Bilanzierungsgebietssummenzeitreihe vom ÜNB — view of NB\n\n\nCustomer backend system\n\nMACO APP · NB\n\nMarket partner\n\n\n\n3.

## Process information Wording of the consolidated version, profile ch. 9.7.1, p. 112.
  1. ### Preconditions The ÜNB has activated the MaBiS-ZP for the BG-SZR (category B) at the BIKO for the time period under consideration.
  2. ### Results The BIKO can determine the data status (the data status depends on the receipt date of the data at the BIKO).
  3. ### Further requirements Aggregated time series that are received from the BIKO after the clearing deadline of the BKA (excluding KBKA) has expired and whose version differs from the highest version with „billing data“ enter the clearing phase for KBKA and are given the data status „check data“.
  4. ### First message **BIKO** sends “Forwarding of BG-SZR (category B)” (step 3). From here on, it is the turn of the party involved on this page.
  5. ### Objective - The BG-SZR (category B) formed by ÜNB is available to BIKO. - The NB has received the BG-SZR (category B) from the BIKO and can check it against its data.
## 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-bilanzierungsgebietssummenzeitreihe-vom-uenb) — BIKO - [View ÜNB](/en/prozessdoku/202610/UENB/MaBiS-uebermittlung-der-bilanzierungsgebietssummenzeitreihe-vom-uenb) — ÜNB · market role UENB *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.
