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

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

**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

**Response per decision tree** - `44053`, `44052` → `E_2005`

### Commitment request

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

**Flow**

Message from **NB** · AS4
**Write endpoint** - Transaction created — [Create process data](/en/api/202604/backend-schreiben-msb/createprocessdata#prozessdaten-erstellen) `POST /createProcessData` Try it out Creates a new transaction in the backend with the data of the incoming message.

### Response to commitment request

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

**Flow**

Message to **NB** · AS4
**Response per decision tree** - `44169` → `E_2006`
**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.

### Continued commitment of the MSB This step runs between other market partners and is not relevant for this view.

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

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

**Check identifiers** - [19003](/en/schnittstellen/202604/pruefi/ORDRSP/PI_19003) — Confirmation of continued commitment · AS4 - [19004](/en/schnittstellen/202604/pruefi/ORDRSP/PI_19004) — Rejection of continued commitment · AS4

**Response per decision tree** - `19003`, `19004` → `E_2004`

### Request to take over the metering location by the gMSB

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

**Flow**

Message from **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 with the data of the incoming message.

## Process information

### First message **NB** sends “Commitment request” (step 3). From here on, it is the turn of the party involved on this page.

## 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 MSBA](/en/prozessdoku/202604/MSB--MSBA/awh-wim-gas-2-0-ende-messstellenbetrieb-vom-msb-an-nb) — the transferring MSB · 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 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. Applies to: [3](#schritt-3) 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: [7](#schritt-7) 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: [4](#schritt-4) For these decision trees of the process there is no source in this format version: - `E_2006` - `E_2004` - `E_2005`
