## Process information
  1. ### First message The party involved on this page is itself the sender of: „Invoice (metering point operation)“ 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 MSBN](/en/prozessdoku/202610/MSB--MSBN/awh-wim-gas-2-0-abrechnung-von-dienstleistungen-im-messwesen) — the receiving MSB · market role MSB - [View NB](/en/prozessdoku/202610/NB/awh-wim-gas-2-0-abrechnung-von-dienstleistungen-im-messwesen) — 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.* :::caution{title="Step sequence reconstructed"} For this process, the BNetzA consolidated version carries no sequence diagram. The steps are reconstructed from the BDEW check identifier table: grouped by the designation, ordered by the process step. The method agrees with the consolidated version in 200 of 200 cases that can be cross-checked — the individual line is nevertheless not editorially reviewed. Check it against the rulebook before adopting it into an implementation specification. ::: 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: [1](#schritt-1), [3](#schritt-3), [5](#schritt-5), [7](#schritt-7), [9](#schritt-9) 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), [4](#schritt-4), [6](#schritt-6), [8](#schritt-8), [10](#schritt-10) 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. Applies to: [1](#schritt-1), [3](#schritt-3), [5](#schritt-5), [7](#schritt-7), [9](#schritt-9)
