# End of metering point operation — GMSB view The use case describes the interactions between the market participants on the occasion of a termination of metering point operation to be initiated by the MSB. The process is also to be applied when a single metering location is decommissioned by a wMSB and gMSB. The NB must ensure uninterrupted metering by involving the gMSB in good time. ## Process flow from the perspective of the MSB (GMSB) \nSystem diagram: Ende Messstellenbetrieb — view of MSB\n\n\nCustomer backend system\n\nMACO APP · MSB (entsprich…\n\nMarket partner\n\n\n\n3.

## Process information Wording of the consolidated version, profile ch. 2.4.1, p. 30.
  1. ### Preconditions Termination of a MSB contract
  2. ### Results - The NB can distribute the master data changed as a result at the metering or market location of a location bundle to the authorised parties (e.g. the wMSB is in a continued commitment), or - the gMSB can serve the use case „[Obligation gMSB](/en/prozessdoku/202610/MSB--GMSB/WiM-Teil1-verpflichtung-gmsb)“.
  3. ### Error case #### Error cases The metering location was not assigned to the MSB.
  4. ### Trigger **Runs beforehand:** [Contract termination of metering point operation](/en/prozessdoku/202610/MSB--MSBA/WiM-Teil1-kuendigung-messstellenbetrieb) — these processes name the one shown here in their result.
  5. ### First message **NB** sends “Commitment request” (step 3). From here on, it is the turn of the party involved on this page.
  6. ### Objective The MSB is no longer assigned to a metering location or has been obliged to continue performing metering point operation.
