Process information
First message The party involved on this page sends this itself: “Request to MSB” to NB (distribution list) (step 1).
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.

Notes on this page 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.
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.
