# Excluded from Delta Detection settings (Business Rule)

**Applies to**  
Platform: Microsoft SQL Server · Snowflake · Snowflake dbt · Databricks · Databricks dbt · Fabric Lakehouse · Fabric Warehouse · Oracle  
Architecture: Data Vault

These business rules check the terms selected in Excluded from Delta Detection of a satellite. A selected term that does not exist raises error ID-10066, which blocks generation in the client. A term that cannot be excluded raises warning ID-10067, and excluding every descriptive term raises warning ID-10068.

### Messages

Each message names the satellite and its type in place of `<model object name>` and `<type>`. The Generate Artifacts page lists the messages without the rule ID.

#### Excluded term does not exist

The client shows an error with this text, with the ID of the missing term in place of `<term id>`:

```
Model object '<model object name>' of type '<type>' has term with
id '<term id>' excluded from delta detection, but no corresponding
term could be found on the model object.
```

On the model object card, point to the error icon to see this message with the rule ID: Error ID-10066.

Cause: Excluded from Delta Detection lists a term that the satellite does not have.  
Fix: open Edit Model Object and remove that entry from Excluded from Delta Detection.

#### Excluded term cannot be excluded

The client shows a warning with this text. `<term name>` is the excluded term, and `<reason>` is either "foreign keys cannot be excluded from delta detection" or "this term does not take part in change detection anyway".

```
Model object '<model object name>' of type '<type>' has term
'<term name>' excluded from delta detection, but <reason>. The
exclusion is ignored.
```

On the model object card, point to the warning icon to see this message with the rule ID: Warning ID-10067.

Cause: the excluded term is a business key, an identity, a foreign key or a Default Term, or it has Historization Type SCD0. The satellite ignores this exclusion and detects changes as before.  
Fix: remove the term from Excluded from Delta Detection.

#### All descriptive terms excluded

The client shows a warning with this text:

```
Model object '<model object name>' of type '<type>' has all its
descriptive terms excluded from delta detection. Changes to these
terms do not create new versions.
```

On the model object card, point to the warning icon to see this message with the rule ID: Warning ID-10068.

Cause: every descriptive term of the satellite is in Excluded from Delta Detection. Descriptive terms are all terms except keys, foreign keys, Default Terms and SCD0 terms.  
Fix: when changes to the satellite should create new versions, remove at least one descriptive term from the list. Otherwise the warning stays.

Available since Generator 2.4.

### Check the result

The error or warning icon is gone from the satellite.

### Example

In a Data Vault project on Microsoft SQL Server, the Satellite `load_caching_hashing` has the Default Term `BG_LoadTimestamp` in Excluded from Delta Detection. The client shows:

```
Model object 'load_caching_hashing' of type 'Satellite' has term
'BG_LoadTimestamp' excluded from delta detection, but this term does
not take part in change detection anyway. The exclusion is ignored.
```
