## 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/GPKE-Teil3-reklamation-einer-definition-des-lf-vom-nb-an-lf) — LF *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.* These read accesses are not listed in the API catalogue of this format version; the step therefore shows only their command, without address and without button. Applies to: [2](#schritt-2) 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)
