## 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-MALO](/en/prozessdoku/202604/MSB/WiM-Teil1-beendigung-rechnungsabwicklung-des-messstellenbetriebes-ueber-den-lf-durch-den-lf) — MSB at the market location object · market role MSB *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 own role was already involved in this process, so the transaction already exists. Applies to: [2](#schritt-2)
