  2. **Load data for the incoming check** - [Read market location](/en/api/202604/backend-lesen/getmarketlocationbasic#marktlokation-lesen) `GET /getMarketLocationBasic` Try it - [Read meter](/en/api/202604/backend-lesen/getcounterbasic#zahler-lesen) `GET /getCounterBasic` Try it
  3. **Write endpoint** - Transaction created — [Create process data](/en/api/202604/backend-schreiben-nb/createprocessdata#prozessdaten-erstellen) `POST /createProcessData` Try it out Creates a new transaction in the backend with the data of the incoming message.

## Process information Wording of the consolidated version, profile ch. 12.5.1, p. 172.
  1. ### Preconditions - The ÜNB has activated the MaBiS-ZP for the DZÜ at the BIKO for the time period under consideration.
  2. ### Results - The NB can check the plausibility of the DZÜ on the basis of the data of the DZÜ list. - The BIKO can determine the data status.
  3. ### First message **BIKO** sends “Forwarding of DZÜ” (step 3). From here on, it is the turn of the party involved on this page.
  4. ### Objective - The DZÜ formed by the ÜNB is available at the BIKO. - The NB has received the DZÜ 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/202604/BIKO/MaBiS-uebermittlung-des-deltazeitreihenuebertrags-vom-uenb-an-biko-und-nb) — BIKO - [View ÜNB](/en/prozessdoku/202604/UENB/MaBiS-uebermittlung-des-deltazeitreihenuebertrags-vom-uenb-an-biko-und-nb) — 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.
