# Transmission of data status for the balancing group aggregated time series from BIKO to NB and BKV — BIKO view The BIKO transmits the data status to the NB and BKV for the BK-SZR (category A) - after receipt of the BK-SZR (category A) from the NB or - after receipt of the validation notification from the BKV or - after use of the aggregated time series for the BKA (without KBKA) or the KBKA. The data status is sent regardless of whether it has changed or not. ## Process flow from the perspective of the BIKO \nSystem diagram: Übermittlung Datenstatus für die Bilanzkreissummenzeitreihe vom BIKO an NB und BKV — view of BIKO\n\n\nCustomer backend system\n\nMACO APP · BIKO\n\nMarket partner\n\n\n\n1.

## Process information Wording of the consolidated version, profile ch. 10.11.1, pp. 137–138.
  1. ### Preconditions - The BIKO has a BK-SZR (category A) transmitted by the NB. - The BIKO has forwarded the BK-SZR (category A) transmitted by the NB to the BKV.
  2. ### Results All systems of BKV, BIKO and NB hold the same data status for a version of the aggregated time series.
  3. ### Error case #### Result in the error case The BIKO informs all affected market participants and, after the error has been corrected, ensures that the correct data status is assigned to all affected BK-SZR (category A). #### Error cases The algorithm applied by the BIKO for assigning the data status is faulty.
  4. ### First message The party involved on this page is itself the sender of: „Data status“ to **BKV** (step 1).
  5. ### Objective The data status managed by the BIKO is available at the NB and at the BKV for the BK-SZR (category A).
## 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 NB](/en/prozessdoku/202610/NB/MaBiS-uebermittlung-datenstatus-fuer-die-bilanzkreissummenzeitreihe-vom-biko-an-nb-und-bkv) — NB - [View BKV](/en/prozessdoku/202610/BKV/MaBiS-uebermittlung-datenstatus-fuer-die-bilanzkreissummenzeitreihe-vom-biko-an-nb-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 source does not yet name the event that triggers these steps. Applies to: [1](#schritt-1), [2](#schritt-2) 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.
