## Process information
  1. ### First message The party involved on this page sends this itself: “Subscribing to normalized profiles or profile sets” to **NB** (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/202610/NB/MaBiS-start-eines-abonnements-von-normierten-profilen-und-profilscharen-vom-lf-bzw-uenb-an-nb) — NB *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.* 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.
