Metering location change from NB to MSB — NB view
The process describes the interactions between the NB and MSB of the metering location in the case where the NB orders a change to technical equipment of the metering location without a change of MSB taking place at the same time. The MSB of the metering location checks whether a metering location change has to be carried out on the basis of the order issuance by the NB. The MSB of the metering location also checks without delay whether the desired change date named with the order issuance can be met for technical or operational reasons. Where necessary, it must promptly agree a date with the AN for this purpose. If it is foreseeable that the date cannot be met, it determines the next possible date on which the desired change can be made. Once the checks have been carried out, the MSB of the metering location replies to the NB within the deadline with an order confirmation or a rejection.

Process information
Wording of the consolidated version, profile ch. 3.3.1.1, pp. 51–52.
Preconditions
The NB can demand a change of the metering location from the MSB of the metering location if and to the extent that it is entitled to do so on the basis of legal provisions or bilateral agreements with the MSB of the metering location. Possible reasons include: a) changed requirements for the metering equipment in accordance with the minimum technical requirements of the NB applicable to the metering location, due to: a. a change of the grid usage contract between the NB and the grid user (LF or AN), b. a change of the consumption behaviour of the AN, c. structural changes affecting the metering location; b) a change of the minimum technical requirements of the NB due to changed legal provisions.
Results
- If the order issuance is confirmed by MSB of the metering location and the change at the metering location has been carried out successfully, MSB of the metering location sends the changed master data.
- The changes carried out in this use case may, among other things, result in a transmission of values being required. For this purpose the SD „Processing and transmission of values from the MSB of the metering location“ (WiM part 2) is carried out. The order issuance for the transmission of values results from the values of the corresponding master data item. No further order issuance is made towards MSB.
Error case
Result in the error case
If the MSB of the metering location was not able to carry out the change on time (e.g. because the measuring equipment was permanently unreachable), it notifies the NB that the change has failed.
Further requirements
Note: The process steps required when ordering a configuration (e.g. change of balancing procedure, metering time period definition of the NB) are not to be triggered via this process; they must be triggered via the use cases of the chapter „Order placement of a configuration“ (GPKE part 3). The creation of the device-related prerequisites for ordering a configuration via these GPKE use cases can, where applicable, be commissioned via the use cases described here for changing the metering location or as part of the device replacement.
First message
The party involved on this page is itself the sender of: „Order issuance for change“ to MSB (corresponds to MSB on the metering location object) (step 1).
Objective
The change to the metering location ordered by the NB has been carried out by the MSB of the metering location.

Notes on this page
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. The numbers are those of the source; where one is missing, it is missing there.
The source does not yet name the event that triggers these steps.

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.
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.
