# Map Fields and Generate Data Lake Objects

Review existing data lake object (DLO) mappings and create DLOs for any unmapped source objects.

This step has two tabs: **Mapped** for source objects already mapped to a DLO, and **Require Action** for source objects that need a DLO.

1. On the **Mapped** tab, review the source objects already mapped to a DLO in Data 360.
    
    ![Mapping source objects to target DLOs](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-analytics-bi-264-0-0-production-enus/ec791473-f5b4-4f64-a656-9104f455d966/bi/images/bi/bi_analytics_metadata_bridge_new_sm_field_mapping_dlo_gen.png)
    
    Click **Review Fields** on any row to review the mapped fields for that object.
2. On the **Require Action** tab, identify source objects that don't yet have a corresponding DLO in Data 360.
    
    ![Selecting the option to set up DLO](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-analytics-bi-264-0-0-production-enus/ec791473-f5b4-4f64-a656-9104f455d966/bi/images/bi/bi_analytics_metadata_bridge_new_sm_selecting_setup_target_dlo.png)
    
    1. For each source object that you want to include, click **Setup Data Lake Object**.
        
        ![Setup DLO modal](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-analytics-bi-264-0-0-production-enus/ec791473-f5b4-4f64-a656-9104f455d966/bi/images/bi/bi_analytics_metadata_bridge_new_sm_setup_dlo_modal.png)
    2. In the **Setup Data Lake Object** dialog, review and confirm the pre-filled values for the object label, data stream name, object API name, and primary key.
    3. Select an **Object Category**.
        
        Most DLOs use **Other**. For more information, see [Category](https://help.salesforce.com/s/articleView?id=data.c360_a_category.htm&language=en_US).
    4. Click **Generate Data Lake Object**.
3. After the bridge generates all missing DLOs, the **Require action** tab is disabled and you can click **Next** to proceed
    
    You’re not required to create DLOs for all source objects before continuing, but the bridge excludes unmapped source objects from the generated semantic model.

Continue to [Map Fields for Data Model Object Generation](https://help.salesforce.com/s/articleView?id=analytics.bi_analytics_metadata_bridge_map_fields_dmo.htm&release=264.0.0&type=5 "Review existing data model object (DMO) mappings and create DMOs for any unmapped source objects.").
