[Business Rules](https://knowledge.bigenius-x.com/best-practices?hsLang=en#business-rules) # No delete detection with an incremental load in the source (Business Rule) **Applies to** Platform: Microsoft SQL Server · Snowflake · Databricks · Fabric Lakehouse · Fabric Warehouse · Oracle Architecture: Data Store This business rule warns when a Store Entity uses delete detection without a Delete Detection Source while a source model object is loaded incrementally. It raises a warning, and generation continues. The rule ID is ID-10045. ### Message The client shows a warning with this text on the model object. `` and `` stand for its name and type. ``` Model object '' of type '' has source objects, which are loaded incrementally and has no delete detection source configured. This might lead to unexpected results. ``` On the model object card, point to the warning icon to see this message with the rule ID: Warning ID-10045. The Generate Artifacts page lists the message without the ID. ### Cause Delete Detection Method of the Store Entity is not `None`, Delete Detection Source is empty, and a source model object of its dataflows maps the Default Term `BG_IncrementalFilter`, which makes it an incremental load. The rule checks only the source model objects that the Store Entity reads directly. ### Fix Do one of the following in Edit Model Object of the Store Entity: - Select a model object that delivers the business keys for delete detection in Delete Detection Source. With `FullSet`, it must deliver the full set of valid business keys. - Set Delete Detection Method to `None`. ### Check the result The warning icon is gone from the Store Entity. ### Example In a Data Store project on Microsoft SQL Server, the Store Entity `load_incremental_source` gets Delete Detection Method `FullSet` without a Delete Detection Source. Its source model object `salestransaction_inc` is loaded incrementally. The client shows: ``` Model object 'load_incremental_source' of type 'Store Entity' has source objects, which are loaded incrementally and has no delete detection source configured. This might lead to unexpected results. ``` ### Related articles - Reference: [Delete Detection Method (Model Object)](https://knowledge.bigenius-x.com/delete-detection-method?hsLang=en), [Delete Detection Source (Model Object)](https://knowledge.bigenius-x.com/delete-detection-source-model-object?hsLang=en), [BG\_IncrementalFilter](https://knowledge.bigenius-x.com/bg_incrementalfilter?hsLang=en) -
