[Business Rules](https://knowledge.bigenius-x.com/best-practices?hsLang=en#business-rules) # Dataflows amount (Business Rule) **Applies to** Platform: Microsoft SQL Server · Snowflake · Snowflake dbt · Databricks · Databricks dbt · Fabric Lakehouse · Fabric Warehouse · Oracle This business rule checks the number of dataflows of a model object. It raises an error, which blocks generation in the client until you fix it. The rule ID is ID-10000. ### Message The client shows an error with this text on the model object. `` and `` stand for its name and type, `` for the allowed number, for example `exactly 1` or `above or equal to 1`. ``` Model object '' of type '' has the wrong amount of dataflows defined. The amount of dataflows should be . ``` On the model object card, point to the error icon to see this message with the rule ID: Error ID-10000. The Generate Artifacts page lists the message without the ID. ![Error popup of a Current View card with Error ID-10000 and the message details](https://knowledge.bigenius-x.com/hs-fs/hubfs/image-png-Sep-18-2024-01-05-07-5892-PM.png?width=636&height=157&name=image-png-Sep-18-2024-01-05-07-5892-PM.png) ### Cause The model object has fewer or more dataflows than its type allows: - Exactly one: Stage, Store Composite, Core Composite, Mart Composite, Mart Out, Mart Hierarchy Flatten, PIT, Current View, History View, RawVault Composite, Vault Out, Hierarchy Flatten and the Business Vault variants of these Data Vault types. - At least one: Store Entity, Entity, Fact, Mart Dimension, Mart Fact, Reference Table and the Hub, Link and satellite types of Data Vault. ### Fix 1. Open Manage Term Mappings of the model object. 2. Delete the extra dataflows, or add a dataflow to a model object without one, see [Delete a Dataflow](https://knowledge.bigenius-x.com/delete-a-data-flow?hsLang=en) and [Add a Dataflow](https://knowledge.bigenius-x.com/add-a-data-flow?hsLang=en). The error disappears. ### Check the result The error icon is gone from the model object, and generation is no longer blocked by it. ### Example In a Data Mart project on Microsoft SQL Server, the Mart Out `dataflow_multi_cached_mo` gets a second dataflow. The client shows: ``` Model object 'dataflow_multi_cached_mo' of type 'Mart Out' has the wrong amount of dataflows defined. The amount of dataflows should be exactly 1. ``` ### Related articles - See also: [Add a Dataflow](https://knowledge.bigenius-x.com/add-a-data-flow?hsLang=en), [Delete a Dataflow](https://knowledge.bigenius-x.com/delete-a-data-flow?hsLang=en), [Understand Dataflow, Dataflow Set and Dataflow Set Model Object](https://knowledge.bigenius-x.com/understand-dataflow-dataflow-set-and-dataflow-set-model-object?hsLang=en), [Dataflow Sets amount (Business Rule)](https://knowledge.bigenius-x.com/dataflow-sets-amount-business-rule?hsLang=en), [Understand warnings and errors](https://knowledge.bigenius-x.com/understand-warnings-and-errors?hsLang=en) -
