**Check identifiers** - [13008](/en/schnittstellen/202610/pruefi/MSCONS/PI_13008) — Load curve (gas)
**Flow**
  1. Message from **NB**
  2. **Load data for the incoming check** - [Read market location](/en/api/202610/backend-lesen/getmarketlocationbasic#marktlokation-lesen) `GET /getMarketLocationBasic` Try it - [Read metering location](/en/api/202610/backend-lesen/getmeterlocationbasic#messlokation-lesen) `GET /getMeterLocationBasic` Try it - [Read meter](/en/api/202610/backend-lesen/getcounterbasic#zahler-lesen) `GET /getCounterBasic` Try it
  3. **APERAK checks** - `13008` → `Z33` — APERAK check: Is referenced message known ? - `13008` → `MSCONS` - `13008` → `Z30`
  4. **Write endpoint** - Transaction created — [Create process data](/en/api/202610/backend-schreiben-lf/createprocessdata#prozessdaten-erstellen) `POST /createProcessData` Try it out Creates a new transaction in the backend with the data of the incoming message.
## Process information
  1. ### First message **NB** sends “Values” (step 1). From here on, it is the turn of the party involved on this page.
## 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 NB](/en/prozessdoku/202610/NB/awh-wim-gas-2-0-ubermittlung-von-werten-vom-nb-an-lf) — NB *The source provides no use case profile for this process — objective, precondition and result are not recorded there.* *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.* :::caution{title="Step sequence reconstructed"} For this process, the BNetzA consolidated version carries no sequence diagram. The steps are reconstructed from the BDEW check identifier table: grouped by the designation, ordered by the process step. The method agrees with the consolidated version in 200 of 200 cases that can be cross-checked — the individual line is nevertheless not editorially reviewed. Check it against the rulebook before adopting it into an implementation specification. :::
