  2. **Write endpoint** - Transaction created — `ERSTELLEN_PROZESSDATEN` Creates a new transaction in the backend with the data of the incoming message.
## Process information Wording of the consolidated version, profile ch. 16.2.1, pp. 215–216.
  1. ### Preconditions - The ÜNB has been informed by the NB responsible for the BG about the assignment of the first market location with ÜNB aggregation responsibility, for whose assigned combination of ZRT, BK and RZ no MaBiS-ZP for the BK-SZR (category C) is activated yet.
  2. ### Results The BKV can assign the BK-SZR (category C) to a MaBiS-ZP.
  3. ### First message **ÜNB** sends “Activation of a MaBiS-ZP for the BK-SZR (Category C)” (Step 1). From here on, the party involved on this page takes its turn.
  4. ### Objective The ÜNB has activated the MaBiS-ZP for the corresponding BK-SZR (category C) at the BKV.
## 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 ÜNB](/en/prozessdoku/202610/UENB/MaBiS-aktivierung-eines-mabis-zaehlpunkts-fuer-die-taegliche-bilanzkreissummenzeitreihe-vom-uenb-an-bkv) — 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. Applies to: [1](#schritt-1) 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. Applies to: [1](#schritt-1)
