It raises an error, which blocks generation in the client until you fix it. The rule ID is ID-10018. ### Message The client shows an error with this text on the model object. `` and `` stand for its name and type, `` for its Implementation Type and `` for the values the type supports. ``` Model object '' of type '' has unsupported implementation type '' defined. Supported implementation types are: . ``` On the model object card, point to the error icon to see this message with the rule ID: Error ID-10018. The Generate Artifacts page lists the message without the ID. ![Error popup of a Stage card with Error ID-10018 and the message details](https://knowledge.bigenius-x.com/hs-fs/hubfs/image-png-Sep-18-2024-01-57-19-4743-PM.png?width=641&height=159&name=image-png-Sep-18-2024-01-57-19-4743-PM.png) ### Cause The Implementation Type of the model object is not one of the values its type supports: - `Cached`, `Virtual`: Stage, Store Composite, Core Composite, Mart Composite, Mart Out, RawVault Composite, BusinessVault Composite and Vault Out. A Stage that loads files or reads through OpenQuery or JDBC supports only `Cached`; a Stage that loads files on Snowflake supports `Cached` and `Permanent`. - `Cached`, `Permanent`: Mart Dimension, PIT and Business PIT. - `Permanent`: Store Entity, Entity, Reference Table and the Hub, Link and satellite types. - `FactLoadStrategy`: Fact and Mart Fact. ### Fix 1. Open Edit Model Object. 2. Set Implementation Type to one of the values in the details and save. 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 Dimension `scd_2_cached` has Implementation Type `Virtual`, a value the client does not offer for a Mart Dimension. The client shows: ``` Model object 'scd_2_cached' of type 'Mart Dimension' has unsupported implementation type 'Virtual' defined. Supported implementation types are: Cached, Permanent. ``` ### Related articles - Reference: [Implementation Type (Model Object)](https://knowledge.bigenius-x.com/implementation-type-model-object?hsLang=en) -
