+
+## Project Codes
+
+A project code is a unique identifier assigned to a specific  project, which helps in tracking and organizing project-related activities and resources. It enables easy retrieval of project-related data and facilitates project management and reporting.
+
+Individual orders (such as [Purchase Orders](./purchase_order.md) or [Sales Orders](./sales_order.md)) can be assigned a *Project Code* to allocate the order against a particular internal project.
+
+### Managing Project Codes
+
+Management of project codes (such as creating or editing codes) is accessed via the [settings page](../settings/global.md). Select the *Project Codes* tab to access project code configuration options:
+
+{% with id="project_codes", url="settings/project_codes.png", description="Project Codes List" %}
+{% include "img.html" %}
+{% endwith %}
+
+#### Enable Project Code Support
+
+By default, project code support is disabled. Select the *Enable Project Codes* option to enable support for this feature
+
+## Assigning Project Codes
+
+Project codes can be assigned to an order when the order is created, or at any later stage by simply editing the order. If project code support is enabled, a *Project Code* field is available in the order details form:
+
+{% with id="assign_project_code", url="order/assign_project_code.png", description="Assign Project Code" %}
+{% include "img.html" %}
+{% endwith %}
+
+## Filtering by Project Codes
+
+The order tables can be easily filtered or sorted by project code:
+
+{% with id="filter-by-project", url="order/filter_by_project.png", description="Filter by Project Code" %}
+{% include "img.html" %}
+{% endwith %}
