+Compute the quantity of a Production Line using a formula defined in the BoM Line.

+
+Configuration
+=============
+
+In any BoM line, fill the `Quantity Formula` field.
+
+The following values are available:
+
+- `bom_line`: the current BoM line,
+- `production`: the production order being created,
+- `product`: the Product of current BoM line,
+- `product_uom_qty`: the quantity of the production order line,
+- `product_uom`: the UoM of the Product of current BoM line,
+- `operation`: the operation where the components are consumed for current BoM line,
+
+The computed quantity must be assigned to the `quantity` variable.
+
+Usage
+=====
+
+This module can be used to customize the quantity of a component based on a custom attribute value selected on the product.
+The following configuration works when the `website_sale` module is installed.
+
+In order to do that, configure as follows:
+
+#. Create an attribute "Component quantity" with a custom value
+
+   .. image:: https://raw.githubusercontent.com/OCA/manufacture/16.0/mrp_bom_line_formula_quantity/static/description/images/product_attribute.png
+
+#. Create and publish a Product having the configured custom value, and the MTO route (archived by default)
+
+   .. image:: https://raw.githubusercontent.com/OCA/manufacture/16.0/mrp_bom_line_formula_quantity/static/description/images/product_tab_attributes.png
+#. Add a BoM to the product, where one Component has the following formula for the quantity:
+
+   .. image:: https://raw.githubusercontent.com/OCA/manufacture/16.0/mrp_bom_line_formula_quantity/static/description/images/bom.png
+
+   .. code-block:: python
+
+      sale_lines = production.move_dest_ids.sale_line_id
+      produced_template = production.product_tmpl_id
+      produced_template_sale_line = sale_lines.filtered(lambda l: l.product_template_id == produced_template)
+      custom_attributes_values = produced_template_sale_line.product_custom_attribute_value_ids.with_context(lang=None)
+      component_quantity_attribute_value = custom_attributes_values.filtered(
+          lambda av: av.custom_product_template_attribute_value_id.attribute_id.name == "Component quantity"
+      )
+      component_quantity = component_quantity_attribute_value.custom_value
+      quantity = int(component_quantity)
+
+#. In the e-commerce, select a quantity for the custom value and buy the product
+
+   .. image:: https://raw.githubusercontent.com/OCA/manufacture/16.0/mrp_bom_line_formula_quantity/static/description/images/website_sale_product.png
+
+#. Confirm the sale order
+
+   .. image:: https://raw.githubusercontent.com/OCA/manufacture/16.0/mrp_bom_line_formula_quantity/static/description/images/sale_order.png
+
+a Production order with the selected value of Component will be created
