# Transmission of the balancing group aggregated time series from NB to BIKO and BKV — NB view The NB delivers the BK-SZR (category A) for the time period under consideration to the BIKO. The BIKO forwards the BK-SZR (category A) to the BKV, provided it is not to be rejected. ## Process flow from the perspective of the NB \nSystem diagram: Übermittlung der Bilanzkreissummenzeitreihe vom NB an BIKO und BKV — view of NB\n\n\nCustomer backend system\n\nMACO APP · NB\n\nMarket partner\n\n\n\n1.

**Check identifiers** - [13003](/en/schnittstellen/202610/pruefi/MSCONS/PI_13003) — Aggregated time series · AS4
**Flow**
  1. Message to **BIKO** · AS4
  2. **Write endpoint** - Transaction updated — [Update process data](/en/api/202610/backend-schreiben-nb/updateprocessdata#prozessdaten-aktualiseren) `POST /updateProcessData` Try it out Updates the existing transaction in the backend once the message has been created.
### Response
**Check identifiers** - [21002](/en/schnittstellen/202610/pruefi/IFTSTA/PI_21002) — Refusal · AS4
**Flow**
  1. Message from **BIKO** · AS4
    **Response per decision tree** - `21002` → [E_0038](/en/referenz/202610/ebd/E_0038) · BIKO · Check balancing group aggregated time series (category A)
  2. **APERAK checks** - `21002` → `Z33`
  3. **Write endpoint** - Transaction updated — [Update process data](/en/api/202610/backend-schreiben-nb/updateprocessdata#prozessdaten-aktualiseren) `POST /updateProcessData` Try it out Updates the existing transaction in the backend with the data of the incoming message.
### Forwarding of BK-SZR (category A) This step runs between other market partners and is not relevant for this view.

## Process information Wording of the consolidated version, profile ch. 10.9.1, pp. 133–134.
  1. ### Preconditions The NB has activated the MaBiS-ZP for the BK-SZR (category A) with 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. ### Error case #### Error cases - The deadline has been exceeded. - The MaBiS-ZP is not active.
  4. ### Further requirements Irrespective of the balancing procedure, the NB has to transmit the DBA for the respective BG to the BIKO. Aggregated time series that are received by the BIKO after the clearing deadline of the BKA (without KBKA) has expired and whose version differs from the highest version with “billing data” enter the clearing phase for the KBKA and are given the data status “check data”.
  5. ### First message The party involved on this page is itself the sender of: „Transmission of BK-SZR (category A)“ to **BIKO** (step 1).
  6. ### Objective - The BK-SZR (category A) formed by NB is available to BIKO. - The BKV has received the BK-SZR (category A) 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-bilanzkreissummenzeitreihe-vom-nb-an-biko-und-bkv) — BIKO - [View BKV](/en/prozessdoku/202610/BKV/MaBiS-uebermittlung-der-bilanzkreissummenzeitreihe-vom-nb-an-biko-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) 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)
