Create an Entity Type

Add a new entity type to your data model and map it to a Polarion work item type.

Configure a Relationship

Define relationships between entity types with link roles and navigation properties.

Configure Constraints

Scope entity loading, creation, and picker filters using constraint rules.

Set Entity Permissions

Control read and write access at the entity and property level.

Advanced Guides

Create Bidirectional Links — Set up forward and reverse navigation properties for full two-way traversal
Configure Many-to-Many Relationships — Handle complex multi-item relationships between entity types
Validate Your Data Model — Check your data model for naming errors, missing references, and configuration issues

For a new data model, follow these guides in sequence: Create an Entity Type first (which includes Polarion type mapping and property definitions), and then Configure a Relationship. Add constraints and permissions after the basic structure is working.
