# Transmission of grid load time series — ÜNB view For the previous day or the previous days, the responsible NB transmits the grid load time series to the NB of the neighbouring BG and to the competent ÜNB responsible for the control area. ## Process flow from the perspective of the ÜNB \nSystem diagram: Übermittlung Netzgangzeitreihe — view of ÜNB\n\n\nCustomer backend system\n\nMACO APP · ÜNB\n\nMarket partner\n\n\n\n3.

**Check identifiers** - [13018](/en/schnittstellen/202610/pruefi/MSCONS/PI_13018) — Load curve metering location, grid coupling point, grid location · AS4
### Transmission of grid load time series
**Check identifiers** - [13018](/en/schnittstellen/202610/pruefi/MSCONS/PI_13018) — Load curve metering location, grid coupling point, grid location · AS4
**Flow**
  1. Message from **NB (responsible NB)** · AS4
  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. 5.7.1, p. 56.
  1. ### Preconditions - The metering point with the identifier „metering point identifier“ for the grid load time series has been replaced.
  2. ### Results - The exchange of the grid time series can take place. - The grid time series can be checked for plausibility or created.
  3. ### First message **NB (responsible NB)** sends “Transmission of the grid load time series” (step 3). From here on, the party involved on this side is the one to act.
  4. ### Objective The neighboring NB and the ÜNB have the grid load time series.
## 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 NBB](/en/prozessdoku/202610/NB--NBB/MaBiS-uebermittlung-netzgangzeitreihe) — neighbouring grid operator · market role NB - [View NBV](/en/prozessdoku/202610/NB--NBV/MaBiS-uebermittlung-netzgangzeitreihe) — responsible grid operator · market role NB *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 numbers are those of the source; where one is missing, it is missing there.* 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: [3](#schritt-3) 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: [3](#schritt-3)
