 ## BOM Generation
+
 The bill of materials is an essential part of the documentation that needs to be sent to the factory. A simple csv export is OK to be important into SMT machines. But for human readable documentation it might not be sufficient. Additional information is needed. The Inventree report system allows to generate BOM well formatted BOM reports.

+### Context variables
+| Variable | Description |

+| bom_items...reference | Reference designators of the part |

+#### Pick List
+
+When all material has been allocated someone has to pick all things from the warehouse. 
+In case you need a printed pick list you can use the following template. This it just the 
+table. All other info and CSS has been left out for simplicity. Please have a look at the 
+BOM report for details.
+
+{% raw %}
+```html
+<table class='changes-table'>
+  <thead>
+    <tr>
+      <th>Original IPN</th>
+      <th>Allocated Part</th>
+      <th>Location</th>
+      <th>PCS</th>
+    </tr>
+  </thead>
+  <tbody>
+  {% for line in build.allocated_stock.all %}
+    <tr>
+      <td> {{ line.bom_item.sub_part.IPN }} </td>
+      {% if line.stock_item.part.IPN != line.bom_item.sub_part.IPN %}
+        <td class='chg'> {{ line.stock_item.part.IPN }} </td>
+      {% else %}
+        <td> {{ line.stock_item.part.IPN }} </td>
+      {% endif %}
+      <td> {{ line.stock_item.location.pathstring }} </td>
+      <td> {{ line.quantity }} </td>
+    </tr>
+  {% endfor %}
+  </tbody>
+</table>
+```
+{% endraw %}
+
+Here we have a loop that runs through all allocated parts for the build. For each part
+we list the original IPN from the BOM and the IPN of the allocated part. These can differ
+in case you have substitutes or template/variants in the BOM. In case the parts differ
+we use a different format for the table cell e.g. print bold font or red color. 
+For the picker we list the full path names of the stock locations and the quantity
+that is needed for the build. This will result in the following printout:
+
+{% with id="report-options", url="report/picklist.png", description="Picklist Example" %} {% include "img.html" %} {% endwith %}
+
+For those of you who would like to replace the "/" by something else because it is hard 
+to read in some fonts use the following trick:
+
+{% raw %}
+```html
+ <td> {% for loc in line.stock_item.location.path %}{{ loc.name }}{% if not forloop.last %}-{% endif %}{% endfor %} </td>
+```
+{% endraw %}
+
+Here we use location.path which is a query set that contains the location path up to the
+topmost parent. We use a loop to cycle through that and print the .name of the entry followed
+by a "-". The foorloop.last is a Django trick that allows us to not print the "-" after
+the last entry. The result looks like here:
+
+{% with id="report-options", url="report/picklist_with_path.png", description="Picklist Example" %} {% include "img.html" %} {% endwith %}
+
+Finally added a `{% raw %}|floatformat:0{% endraw %}` to the quantity that removes the trailing zeros.

+## Return Orders
+
+Return Orders allow stock items (which have been sold or allocted to a customer) to be to be returned into stock, typically for the purpose of repair or refund.
+
+!!! tip "An Order By Any Other Name"
+    A Return Order may also be known as an [RMA](https://en.wikipedia.org/wiki/Return_merchandise_authorization) 
+
+### Enable Return Order Functionality
+
+By default, Return Order functionality is not enabled - it must be enabled by a *staff* user from the settings page:
+
+{% with id="enable-return-order", url="sell/return_order_enable.png", description="Enable Return Orders" %}
+{% include "img.html" %}
+{% endwith %}
+
+Once this setting is enabled, you can access the "Return Orders" page from the main navigation bar:
+
+{% with id="return-order-navbar", url="sell/return_order_navbar.png", description="Access Return Orders" %}
+{% include "img.html" %}
+{% endwith %}
+
+### Return Order Permissions
+
+[Permissions](../settings/permissions.md) for Return Orders are managed via the `return_order` permission group. Users are assigned appropriate permissions based on the groups they are part of.
+
+### View Return Orders
+
+A list of Return Orders is displayed on the *Return Order* index page:
+
+{% with id="return-order-index", url="sell/return_order_index.png", description="Return Order Index" %}
+{% include "img.html" %}
+{% endwith %}
+
+Various filters are available to configure which orders are displayed, and how they are arranged.
+
+### Return Order Status Codes
+
+Each Return Order has a specific status code, as follows:
+
+| Status | Description |
+| --- | --- |
+| Pending | The return order has been created, but not sent to the customer |
+| In Progress | The return order has been sent to the customer |
+| Complete | The return order was marked as complete |
+| Cancelled | The return order was cancelled |

+
+The Return Order can be edit by selecting the <span class='fas fa-edit'></span> icon under the <span class='fas fa-tools'></span> actions menu.
+
+### Line Items
+
+Return Order line items can be added while the [status](#return-order-status-codes) of the order is *In Progress*. Any stock item which is currently sold or assigned to the particular customer can be selected for return.
+
+!!! info "Serialized Stock Only"
+    Only stock items which are serialized can be selected for return from the customer
