**Flow**
  1. Message to **MSB** · AS4
  2. **Write endpoint** - Transaction updated — [Update process data](/en/api/202604/backend-schreiben-nb/updateprocessdata#prozessdaten-aktualiseren) `POST /updateProcessData` Try it out Updates the existing transaction in the backend once the message has been created.
## Process information
  1. ### First message The party involved on this page is itself the sender of: „Information“ to **MSB** (step 1).
## 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 MSB](/en/prozessdoku/202604/MSB/geli-gas-2-0-ubermittlung-von-informationen) — MSB *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. ::: The source does not yet name the event that triggers these steps. Applies to: [1](#schritt-1)
