[Business Rules](https://knowledge.bigenius-x.com/best-practices?hsLang=en#business-rules) # Invalid data type configuration (Business Rule) **Applies to** Platform: Microsoft SQL Server · Snowflake · Snowflake dbt · Databricks · Databricks dbt · Fabric Lakehouse · Fabric Warehouse · Oracle This business rule checks that the length, precision and scale of every term's data type are allowed on the target platform. A term that breaks the rule gets a warning; the generator writes the values anyway, and the target platform can reject the table at deployment. After the fix, the warning is gone and the table deploys. ### Message Warning with the ID of the platform: ID-32010 (Microsoft SQL Server), ID-33002 (Oracle), ID-30005 (Snowflake, Snowflake dbt), ID-31000 (Databricks, Databricks dbt, Fabric Lakehouse), ID-35000 (Fabric Warehouse). The short text is `Model object contains invalid data type configurations.`, followed by the rule, for example: ``` Model object '' of type '' has invalid 'nvarchar' column(s) defined. Data type 'nvarchar' does only support 'Length' between 1 and 4000 and does not support 'Precision' or 'Scale'. ``` The message names the data type and the values it allows. One message is shown per data type and rule, even when several terms break it. Available since Generator 2.2; on Databricks and Fabric Lakehouse since Generator 2.0. ### Cause A term has a length, precision or scale its platform data type does not accept, or lacks a required one. Examples on Microsoft SQL Server: `nvarchar` and `nchar` need a length between 1 and 4000, `varchar` and `varbinary` between 1 and 8000; `decimal` needs a precision between 1 and 38 and a scale not above it; `int` and `date` accept none of the three. On Oracle, `VARCHAR2` accepts a length between 1 and 4000. The check is a warning: the generator still writes the table with the configured values. ### Fix 1. Open the model object in [Edit Model Object](https://knowledge.bigenius-x.com/edit-a-model-object?hsLang=en) or Manage Terms and find the term with the named data type. 2. Set a length, precision or scale in the allowed range, or remove the value the data type does not support. For a Default Term, change it in [Manage Default Terms](https://knowledge.bigenius-x.com/manage-default-terms?hsLang=en). 3. Generate the artifacts again. ### Check the result The warning disappears from the model object, and the table deploys without `Msg 2717`. ### Example The term `CUSTOMER` of the Satellite `load_customer_sat` has the data type `nvarchar` with length 5000. The generator writes `[CUSTOMER] NVARCHAR(5000) NOT NULL`, and the deployment on Microsoft SQL Server stops at the table: ``` Msg 2717, Level 16, State 2: The size (5000) given to the parameter 'CUSTOMER' exceeds the maximum allowed (4000). ``` The views and procedures of the Satellite then fail with `Invalid object name`. With length 4000, the table deploys. ### Related articles - Reference: [Supported Term Data Types (Business Rule)](https://knowledge.bigenius-x.com/supported-term-data-types-business-rule?hsLang=en), [Native Data Type (Term Mapping)](https://knowledge.bigenius-x.com/native-data-type-term-mapping?hsLang=en) -
