| Step | Check | Result | Code | Note |
|---|---|---|---|---|
| 1 | Does the version of the time series of MaBiS-ZP for this balancing month already exist? | yes | A01 | Cluster: Refusal Time series already exists |
| — | — | no | → Step 2 | — |
| 2 | For the version of the time series of the DZÜ for the balancing month, is a DZÜ list with an identical version and an identical balancing month available for this MaBiS-ZP? | no | A02 | Cluster: Rejection DZÜ list not available |
| — | — | yes | → Step 3 | — |
| 3 | Do the energy quantities of the DZÜ match the energy quantities determined on the basis of the check result of the DZÜ list? | no | A03 | Cluster: Rejection Energy quantity incorrect / not plausible |
| — | — | yes | A04 | Cluster: Consent Time series accepted |
## Result codes
| Result code | Cluster | Meaning |
|---|---|---|
| `A01` | Refusal | Time series already exists |
| `A02` | Rejection | DZÜ list not available |
| `A03` | Rejection | Energy quantity incorrect / not plausible |
| `A04` | Consent | Time series accepted |
