| 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 | Do the energy quantities of the AAÜZ match the expected energy quantities? | no | A02 | Cluster: Rejection Energy quantity incorrect / not plausible |
| — | — | yes | A03 | Cluster: Consent Time series accepted |
## Result codes
| Result code | Cluster | Meaning |
|---|---|---|
| `A01` | Refusal | Time series already exists |
