[Default Terms](https://knowledge.bigenius-x.com/generators?hsLang=en#default-terms) # BG\_DataQuality\_ID **Applies to** Platform: Microsoft SQL Server · Snowflake · Snowflake dbt · Databricks · Databricks dbt · Fabric Lakehouse · Fabric Warehouse · Oracle Architecture: Data Store · Data Vault · Dimensional `BG_DataQuality_ID` numbers the rows of a load in the data quality processing of a model object. It links each row of the DataQuality table to its entries in the Error table. ### Objects that carry it The DataQuality table, DataQuality loader and Error table of Store Entity, Entity, Fact and the Hub, Link and satellite types of Data Vault. These parts exist when data quality rules apply to the object, see [Understand Data Quality rules overview](https://knowledge.bigenius-x.com/understand-data-quality-rules-overview?hsLang=en). You do not map it; the generator fills it. ### Value Each row in the DataQuality table gets a new number. The mechanism depends on the platform: - Microsoft SQL Server, Snowflake, Databricks, Oracle: an identity column of the table. - Fabric Warehouse: the loader adds a row number to the highest value in the table. - Fabric Lakehouse: the loader derives the value from the load time and a generated row ID. The DataQuality loader empties the DataQuality table at the start of every load. On Microsoft SQL Server, where emptying the table resets the identity column, the numbering starts again at 1 in every load. The Error table keeps the entries of all loads, so an entry is identified by `BG_DataQuality_ID` together with `BG_LoadTimestamp`. ### Data type - Microsoft SQL Server, Fabric Warehouse: `bigint` - Oracle: `NUMBER` - Snowflake, Snowflake dbt: `INTEGER` - Databricks, Databricks dbt, Fabric Lakehouse: `long` ### Example An Entity on Microsoft SQL Server checks the foreign key to a loyalty card Entity. The same four rows are loaded at 11:00 and at 12:00 UTC. Row 4 references card 999, which does not exist. The Error table then holds: ``` BG_DataQuality_ID BG_LoadTimestamp BG_ErrorDescription 4 2026-10-27 11:00 Missing foreign key value for relation to "common_loyaltycard_scd1" 4 2026-10-27 12:00 Missing foreign key value for relation to "common_loyaltycard_scd1" ``` ### Release differences - Generator 1.10: the term is named `BG_DataQuality_ID`. Up to Generator 1.9 it was named BG\_Cleanse\_ID. ### Related articles - Reference: [BG\_ErrorCount](https://knowledge.bigenius-x.com/bg_errorcount?hsLang=en), [BG\_ErrorDescription](https://knowledge.bigenius-x.com/bg_errordescription?hsLang=en), [BG\_LoadTimestamp](https://knowledge.bigenius-x.com/bg_loadtimestamp?hsLang=en) -
