**As** an Enterprise user,
**I want** to have the option to limit cost types for certain projects
**so that** these are only available in certain projects.

<br>

**Acceptance criteria**

* Add a projects association to every cost type, similar to a custom field

* When editing a cost type

* a new boolean field &quot;For all projects&quot; is added, which is checked in the migration

* This ensures current behavior stays the same

* There is a second tab &quot;Projects&quot;

* This tab behaves identical to the custom field administration, allowing administrators to add cost types

* When inside the project settings

* There is a new menu entry &quot;Time and costs&quot;

* The &quot;Time entry activities&quot; are moved into that menu, as a tab

* A new tab &quot;Cost types&quot; is added, showing a selection list for all cost types similar to time entry activities

* When all cost types are disabled in a project, the option to log and show unit costs is removed

* The edit form and project select is primerized Begin of the insertion

* We remove the rate editing on the index page, in favor of showing rates as a separate tab


End of the insertion Begin of the deletion
