| 10 | Has the MSB granted the NB general consent to carry out a reconnection/disconnection? | yes | A01 | Cluster: Consent General consent of the MSB for the disconnection/reconnection is available. |
| — | — | no | → Step 20 | — |
| 20 | Is there a reason preventing a disconnection at the market location? | yes | A02 | Cluster: Rejection There is a reason for prevention. Note: The identified problem must be described/named in the response. |

*Role of the numbers: »response« are the check identifiers that list this tree in the ebd_code column of the check identifier table (knowledge-collection · FV 202604); »checked« is the difference set to it from the return path of the process steps. The »response check identifier« column of the result codes assigns a cluster only because this tree carries exactly one checked message and exactly one response per pole; their pole comes from the use case title of the response.*
