## Process information Wording of the consolidated version, profile ch. 8.3.1, pp. 91–92.
  1. ### Preconditions - The ÜNB has been informed by the NB responsible for the BG about the ending of the assignment of the last market location with ÜNB aggregation responsibility, for whose assigned combination of BK, ZRT, RZ/BG and LF a MaBiS-ZP for the LF-SZR (category B) is activated, and this MaBiS-ZP is activated at the LF, or - The order cancellation of the aggregation level of a MaBiS-ZP for the BK-SZR (category B) at the level of the RZ to which the LF-SZR (category B) is assigned is available from the BKV.
  2. ### Results - The LF can trigger the forwarding of the deactivated MaBiS-ZP to the BKV, or - in the error case, the LF can initiate a clearing process with the ÜNB.
  3. ### Further requirements After the point in time of deactivation, the MaBiS-ZP can no longer be used until it is activated again for the LF-SZR (category B).
  4. ### First message **ÜNB** sends “Deactivation of a MaBiS-ZP for the LF-SZR (category B)” (step 1). From here on, it is the turn of the party involved on this page.
  5. ### Objective The ÜNB has deactivated the MaBiS-ZP for the LF-SZR (category B) at the LF.
## 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 ÜNB](/en/prozessdoku/202604/UENB/MaBiS-deaktivierung-eines-mabis-zaehlpunkts-fuer-die-lieferantensummenzeitreihe-vom-uenb-an-lf) — ÜNB · market role UENB *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.
