## Belongs to these role views

The check identifier itself carries no market role. This assignment is derived back from the role views in whose process steps it occurs — affected are **LF**, **NB** and **MSB**.

<div className="maco-tabellenrahmen">

| Role | Party involved | Process | Rulebook | Division | Step |
|---|---|---|---|---|---|
| LF | LF | [Master data change initiated by the LF (responsible)](/en/prozessdoku/202604/LF/geli-gas-2-0-stammdatenanderung-vom-lf-verantwortlich-ausgehend) | GeLi Gas 2.0 | Gas | Step 1 |
| NB | NB | [Master data change initiated by the LF (responsible)](/en/prozessdoku/202604/NB/geli-gas-2-0-stammdatenanderung-vom-lf-verantwortlich-ausgehend) | GeLi Gas 2.0 | Gas | Step 1 |
| MSB | MSB | [Master data change initiated by the LF (responsible)](/en/prozessdoku/202604/MSB/geli-gas-2-0-stammdatenanderung-vom-lf-verantwortlich-ausgehend) | GeLi Gas 2.0 | Gas | Step 1 |

:::caution{title="This check identifier is used in 4 contexts"}

Regulatory determination and communication direction depend on the process in which the message is sent. A single entry would be misleading — all placements are therefore listed here.

## Transaction and responses

**Role of this check identifier: request.** Basis: the transaction data carry neither `antwortstatus` nor `antwortstatusCodeliste`, and neither the title nor the action of the Prüfi table begins with “response” or “response message”.

### Which messages respond to this

<div className="maco-tabellenrahmen">

| Role | Check identifier | Use case | Message type | Origin of supply |
|---|---|---|---|---|
| Response | [44121](/schnittstellen/202604/pruefi/UTILMD_GAS/PI_44121) | Response to change from the LF | UTILMD_GAS | explicit |

</div>

This column is the **inverse** of the assignment on the response pages — not the next step of a list. The process source says of its own steps that they are »possible messages, not a sequence«.

**Check identifiers of the same AHB table:** No other check identifier of message type UTILMDG has the same row structure in this version.

<Hinweisbereich>

An **\*** after a field or group name marks a **mandatory field** or a mandatory group. The type is beside it; where the value ends up in the EDIFACT segment is shown by the info icon next to the field name.

The status column carries two vocabularies because the manual answers two questions: on a **group row**, *Muss*, *Soll* or *Kann* states whether the EDIFACT segment must be present; on a **field row**, *X* states that this qualifier is used in this check identifier. Both are kept exactly as the source records them.

For this check identifier, the application handbook lists **62 rows**. They appear in the order of the handbook, indented by segment: a row without a data element opens a segment, the rows below it are its data elements.

The **Condition** column names the markers under which the handbook ties a row to a prerequisite; their free text is below the table.

The test data contains one transaction for this check identifier under the message type `utilmdGas`. Each is stored twice — as a EDIFACT message and as a BO4E JSON. That both representations show the same transaction has been recalculated, not assumed: interchange control reference, message reference number, document number, message date, sender and recipient match in all 517 pairs of the format version; check identifier, transaction number and location ID wherever both representations carry them. Not a single attribute contradicts.

:::note{title="Placeholder from the test data set"}

The test data set carries placeholders instead of valid values: `{{date}}` and `{{time}}` in the UNB interchange envelope of every EDIFACT file. **The page replaces these on call with the current date and the current time** — in the format that applies at the respective position: in the envelope year, month and day as well as hour and minute, two digits each.

`<businessKey>` stays in place. It is not a time value, and an invented key would look like a valid one.
