## Process information
  1. ### First message The party involved on this page is itself the sender of: „Order placement for control command from LF to MSB“ 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 NB](/en/prozessdoku/202604/NB/GPKE-Teil3-steuerbefehl-vom-lf-an-msb-uf-b024) — NB - [View MSB](/en/prozessdoku/202604/MSB/GPKE-Teil3-steuerbefehl-vom-lf-an-msb-uf-b024) — MSB - [View WMSB](/en/prozessdoku/202604/MSB--WMSB/GPKE-Teil3-steuerbefehl-vom-lf-an-msb-uf-b024) — further metering point operator · market role MSB - [View ÜNB](/en/prozessdoku/202604/UENB/GPKE-Teil3-steuerbefehl-vom-lf-an-msb-uf-b024) — ÜNB · market role UENB *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.* The source does not yet name the event that triggers these steps. Applies to: [1](#schritt-1) 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), [3](#schritt-3) For the check identifiers of these steps there is no test case in the test data set; the »Try it out« button of the write interface therefore offers no body.
