Relation fields link records from one object to records in another object. For example: - **People** → **Companies** (each person works for a company) - **Opportunities** → **People** (each deal has a contact person) - **Tasks** → **Opportunities** (each task relates to a specific deal) ## Creating Relation Fields ### 1. Add the Field Go to **Settings → Data Model → [Your Object]** and click **Add Field**. ### 2. Choose Relation Type - **Field Type**: Select "Relation" - **Target Object**: Choose which object to connect to - **Relationship**: Currently supports **1-to-many** relationships only. Make sure to create the relationship in the right direction. ### 3. Configure Field Names You'll need to set names for both sides of the relationship: - **Source field name**: How the field appears on your current object - **Target field name**: How the reverse field appears on the target object Field names cannot be edited once the relation is saved as it impacts the API structure. Choose carefully. ## Relating to Team Members You can create relations to any object, including **Workspace Members** (your Twenty team users). This is useful for creating ownership fields: - **Account Owner**: Link a Company to a team member who manages it - **Deal Owner**: Assign an Opportunity to a specific salesperson When you create a relation to`Workspace Members`, you'll see your team members' names in dropdown selections, making it easy to assign ownership and responsibilities. ## Best Practices - **Plan your relationships** before creating them - **Use clear, descriptive names** for both field names - **Test relationships** with sample data before full implementation ## Upcoming Features - **Morph Many relationships** (Coming Q4 2025) - **Many-to-many relationships** (Coming Q1 2026)
