| Step | Check | Result | Code | Note |
|---|---|---|---|---|
| 10 | Does the requested technology already exist at the location? | yes | A01 | Cluster: Rejection Ordered technology is already in place. |
| — | — | no | → Step 20 | — |
| 20 | Is the MSB still the assigned MSB at the affected location at the start of the requested implementation period? | yes | → Step 30 | — |
| — | — | no | A02 | Cluster: Rejection MSB is no longer assigned to the affected location at the start of the implementation period. |
| 30 | Is the requested technology fundamentally possible at the affected location? | yes | → Step 40 | — |
| — | — | no | A03 | Cluster: Rejection The requested technology is not possible at the location concerned. |
| 40 | Is implementation of the requested technology fundamentally possible within the specified implementation period? | yes | → Step 50 | — |
| — | — | no | A04 | Cluster: Rejection Implementation is not possible within the requested implementation period. Note: An alternative implementation period must be stated. |
| 50 | Can the specified price sheet be accepted in the specified version? | yes | → Step 60 | — |
| — | — | no | A05 | Cluster: Rejection The stated price sheet cannot be accepted in the stated version. |
| 60 | Has a previously unspecified error occurred? | yes | A99 | Cluster: Rejection Other Note: The identified problem must be described/named in the response. End of usability: 01.10.2026 00:00 |

*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.*

**No** consistency check was carried out for this decision tree — no generated BPMN found. Whether the MACO APP implements this tree completely is therefore not evidenced here.
