--- title: No incremental load with a Deduplication (Business Rule) description: "Various Business Rules are checked after a change is made to a Model Object. These checks ensure the integrity and consistency of the model. This Business Rule is no longer used from 1.8 release of Generators. It is replaced by: No deduplication for Stage objects. No incremental load with a Deduplication This Business Rule checks the value of the Deduplication Method property for a Model Object in case of an incremental load configured and several Dataflow Sets. This check has no parameter. If the Business Rule validation fails, the following message will be displayed as a Warning Notification on the Model Object: Model object '{ModelObject.Name}' of type '{ModelObject.ModelObjectType.Name}' has deduplication method '{DeduplicationMethods.Distinct}' and incremental load configured. This might lead to unexpected results. Consider using a Composite Model Object for deduplication." --- [Skip to content](https://knowledge.bigenius-x.com/no-incremental-load-with-a-deduplication-business-rule#main-content) [Contact us](https://knowledge.bigenius-x.com/kb-tickets/new?hsLang=en) [Go to Customer Portal](https://knowledge.bigenius-x.com/customer-portal?hsLang=en) [![TRI\_Logo\_biGENIUS\_2020\_RGB\_s](https://knowledge.bigenius-x.com/hs-fs/hubfs/Marketing/TRI_Logo_biGENIUS_2020_RGB_s.png?width=150&height=42&name=TRI_Logo_biGENIUS_2020_RGB_s.png)](https://www.bigenius-x.com/) Open main navigation Close main navigation - [Contact us](https://knowledge.bigenius-x.com/kb-tickets/new) - [Go to Customer Portal](https://knowledge.bigenius-x.com/customer-portal) How can we help you? - There are no suggestions because the search field is empty. 1.

These checks ensure the integrity and consistency of the model. This Business Rule is no longer used from 1.8 release of Generators. It is replaced by: [No deduplication for Stage objects](https://knowledge.bigenius-x.com/no-deduplication-for-stage-objects?hsLang=en). ### No incremental load with a Deduplication This Business Rule checks the **value of the [Deduplication Method](https://knowledge.bigenius-x.com/deduplication-method-model-object?hsLang=en) property for a Model Object** in case of an **[incremental load](https://knowledge.bigenius-x.com/configure-an-incremental-load?hsLang=en)** configured and **several Dataflow Sets**. This check has no parameter. If the Business Rule validation fails, the following message will be displayed as a **Warning Notification** on the Model Object: > Model object '{ModelObject.Name}' of type '{ModelObject.ModelObjectType.Name}' has deduplication method '{DeduplicationMethods.Distinct}' and incremental load configured. This might lead to unexpected results. Consider using a Composite Model Object for deduplication.
