Device takeover — MSBN view
The MSBN of the metering location requests a device takeover quotation from the MSBA of the metering location. The MSBA of the metering location transmits, free of charge, a quotation for the purchase or use of the technical equipment of the individual metering location requested by the MSBN of the metering location, for the takeover date desired by the MSBN of the metering location. The components of the measuring equipment can be offered individually or in full. The MSBN of the metering location accepts the overall quotation or quotations for individual technical equipment as part of an order placement. Acceptance with regard to individual technical equipment at the same time constitutes implied rejection with regard to the remaining technical equipment offered by the MSBA of the metering location. The MSBA of the metering location confirms the ordered device takeover. If the measuring equipment itself is affected by the device takeover, the MSBA of the metering location transmits the meter reading for the device takeover to the MSBN of the metering location in the case of a kME or mME with active energy metering.

Process information
Wording of the consolidated version, profile ch. 3.2.1, pp. 48–49.
Preconditions
As a result of a MSB change (use case „Start of metering point operation“ or use case „Commitment gMSB“), the MSBN of the metering location or gMSB (represented in this use case as MSBN) of the metering location intends a device takeover.
Results
If the measuring equipment itself is affected by the device takeover, the MSBA of the metering location and MSBN of the metering location carry out the SD „Processing and transmission of values from the MSB of the metering location“ (WiM part 2).
Further requirements
Note: If the measuring equipment itself is affected by the device takeover, the MSB of the market location transmits values to the NB, LF and ÜNB (WiM part 2, chapter 2.4.3. „SD: Processing and transmission of values from the MSB of the market location“). If a market location has several metering locations and not all metering locations are affected by the device replacement and/or a device takeover, the MSB of the market location must, in order to determine the energy quantity of the market location, collect values for the metering locations not affected by the device replacement/device takeover and, where necessary, request them from the MSB of the metering location.
First message
The party involved on this page sends this itself: “Request device takeover quotation” to MSB (corresponds to MSBA at the metering location object) (step 1).
Objective
The interactions for preparing and performing a device takeover between the MSBN of the metering location and the MSBA of the metering location have been completed.
Other views of the process

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.
These read accesses are not listed in the API catalogue of this format version; the step therefore shows only their command, without address and without button.
