## 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 BKV](/en/prozessdoku/202604/BKV/MaBiS-beendigung-des-abonnements-fuer-bilanzkreiszuordnungsliste-vom-bkv-an-nb) — BKV *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 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.
