[Business Rules](https://knowledge.bigenius-x.com/best-practices?hsLang=en#business-rules) # Model object has delta detection ColumnComparison and load caching Hashing defined (Business Rule)     Various **Business Rules** are validated after a change to a **Model Object**. These checks ensure the model's integrity and consistency. ### Model object has 'ColumnComparison' and 'Hashing' This Business Rule checks if the Project Property [**Delta Detection**](https://knowledge.bigenius-x.com/delta-detection-project?hsLang=en) is set to *Column Comparison* and Model Object Property**[Load Caching](https://knowledge.bigenius-x.com/load-caching-model-object?hsLang=en)** is set to *Hashing*. 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 delta detection 'ColumnComparison' and load cashing 'Hashing' defined. With 'ColumnComparison', there is no Hashing View to cash.
