**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_0008](/en/referenz/202610/ebd/E_0008) · BIKO · Check NZR
  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.

## Process information Wording of the consolidated version, profile ch. 5.5.1, p. 52.
  1. ### Preconditions - The MaBiS-ZP for the NZR is activated by the responsible NB at the BIKO for the relevant time period. - The reconciliation of the NZR between the two NB has taken place. - The version of the NZR agreed between the NB is known to the responsible NB.
  2. ### Results The BIKO can take the NZR into account for the calculation of the NB-DZR and transmit the data status (billing data/billing data KBKA) to the two NB.
  3. ### Further requirements The representation of the energy flow directions in the NZR is always transmitted from the point of view of the BG of the responsible NB. Within the BKA, the NZR transmitted to the BIKO is deemed to be the version agreed between the two NB. If there are differences between the agreed version and the NZR transmitted to the BIKO, this is to be clarified bilaterally between the two NB.
  4. ### First message The party involved on this page is itself the sender of: „Transmission of NZR“ to **BIKO** (step 1).
  5. ### Objective The BIKO has the version of the NZR agreed between the two 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-netzzeitreihe) — 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 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)
