**Check identifiers** - [44051](/en/schnittstellen/202604/pruefi/UTILMD_GAS/PI_44051) — End of MSB · AS4

**Flow**

Message to **NB** · AS4
**Write endpoint** - Transaction updated — [Update process data](/en/api/202604/backend-schreiben-msb/updateprocessdata#prozessdaten-aktualiseren) `POST /updateProcessData` Try it out Updates the existing transaction in the backend once the message has been created.

### Response to deregistration

**Check identifiers** - [44053](/en/schnittstellen/202604/pruefi/UTILMD_GAS/PI_44053) — Rejection of end of MSB · AS4 - [44052](/en/schnittstellen/202604/pruefi/UTILMD_GAS/PI_44052) — Confirmation of end of MSB · AS4

**Flow**

Message from **NB** · AS4
**Response per decision tree** - `44053`, `44052` → `E_2005`
**Write endpoint** - Transaction updated — [Update process data](/en/api/202604/backend-schreiben-msb/updateprocessdata#prozessdaten-aktualiseren) `POST /updateProcessData` Try it out Updates the existing transaction in the backend with the data of the incoming message.

### Commitment request This step runs between other market partners and is not relevant for this view.

**Check identifiers** - [44168](/en/schnittstellen/202604/pruefi/UTILMD_GAS/PI_44168) — Commitment request / demand · AS4

### Response to commitment request This step runs between other market partners and is not relevant for this view.

**Check identifiers** - [44169](/en/schnittstellen/202604/pruefi/UTILMD_GAS/PI_44169) — Confirmation commitment request · AS4

**Response per decision tree** - `44169` → `E_2006`

### Continued commitment of the MSB

**Check identifiers** - [17002](/en/schnittstellen/202604/pruefi/ORDERS/PI_17002) — Continued commitment · AS4

## Process information

### First message The party involved on this page sends this itself: “Deregistration” 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 GMSB](/en/prozessdoku/202604/MSB--GMSB/awh-wim-gas-2-0-ende-messstellenbetrieb-vom-msb-an-nb) — default metering point operator · market role MSB - [View NB](/en/prozessdoku/202604/NB/awh-wim-gas-2-0-ende-messstellenbetrieb-vom-msb-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.* :::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. ::: 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), [5](#schritt-5) 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) For these decision trees of the process there is no source in this format version: - `E_2004` - `E_2005` - `E_2006`
