**As an** administrator configuring any work package type (sub-type or plain type)
**I want to** link a type's PDF and subject configuration to a source type or make it independent
**so that** I can reuse an existing set of export templates and subject patterns across many types, or create my own ones

## Scope

The reuse aspect Begin of the insertionof this featureEnd of the insertion Begin of the deletion (`settings_source_id`, resolved by `effective_settings_type`)End of the deletion covers:

* PDF export template configuration Begin of the deletion (`pdf_export_templates_config`),End of the deletion

* subject configuration and identifier patterns Begin of the deletion (`patterns`).End of the deletion


Begin of the deletion It does **not** cover the core type settings, which are inherited from the parent on a sub-type and not editable.

End of the deletion ## Acceptance criteria

* For any type, I can set its PDF and subject configuration to Begin of the insertion

* **Independent**

* End of the insertion Begin of the deletion or **Independent**.End of the deletion A sub-type defaults to Linked to its parent. Begin of the deletion _(F3-C0)_End of the deletion

* A Linked type's PDF and subject configuration resolve to the source at runtime; when I change the source, every linked type reflects it Begin of the insertionimmediatelyEnd of the insertion Begin of the deletion immediately. _(F3-C1)_End of the deletion

* When I switch this configuration to Independent, the system copies the current source's PDF and subject configuration once and then severs the Begin of the insertionlinkEnd of the insertion Begin of the deletion link. _(F3-C2)_End of the deletion

* The system prevents me from creating a cyclic dependency between these Begin of the insertionsourcesEnd of the insertion Begin of the deletion sources. _(F0-C2)_End of the deletion

* The core type settings Begin of the deletion (name, color, `is_milestone`, `is_in_roadmap`, `is_default`)End of the deletion are never part of this aspect; on a sub-type they are inherited from the parent and Begin of the insertionread-onlyEnd of the insertion Begin of the deletion read-only. _(F0-C3)_End of the deletion
