## Process information
  1. ### First message **NB** sends “Forwarding of the cancellation” (step 3). 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 LF](/en/prozessdoku/202604/LF/awh-sperrprozesse-gas-stornieren-der-unterbrechung-und-wiederherstellung-der-anschlussnutzung-auf-anweisung-des-lf) — LF - [View NB](/en/prozessdoku/202604/NB/awh-sperrprozesse-gas-stornieren-der-unterbrechung-und-wiederherstellung-der-anschlussnutzung-auf-anweisung-des-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. :::
