## Process information
  1. ### Trigger **Runs beforehand:** [End of metering point operation](/en/prozessdoku/202610/MSB--GMSB/WiM-Teil1-ende-messstellenbetrieb) — these processes name the one shown here in their result.
  2. ### First message The party involved on this page is itself the sender of: „Confirmation of the takeover of metering point operation“ to **NB** (step 3).
## 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-verpflichtung-gmsb) — 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. The numbers are those of the source; where one is missing, it is missing there.* :::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. ::: The source does not yet name the event that triggers these steps. Applies to: [3](#schritt-3), [4](#schritt-4) 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: [3](#schritt-3)
