## Process information
  1. ### First message **LF** sends “Order placement for control command from LF to MSB” (step 1). From here on, the party involved on this page has the next move.
## 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 WMSB](/en/prozessdoku/202610/MSB--WMSB/GPKE-Teil3-steuerbefehl-vom-lf-an-msb-uf-b024) — further metering point operator · market role MSB - [View LF](/en/prozessdoku/202610/LF/GPKE-Teil3-steuerbefehl-vom-lf-an-msb-uf-b024) — LF - [View NB](/en/prozessdoku/202610/NB/GPKE-Teil3-steuerbefehl-vom-lf-an-msb-uf-b024) — NB - [View ÜNB](/en/prozessdoku/202610/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.

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.
