# 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:

1. Create an attribute “Component quantity” with a custom value

2. Create and publish a Product having the configured custom value, and the MTO route (archived by default)

3. Add a BoM to the product, where one Component has the following formula for the quantity:

       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)

4. In the e-commerce, select a quantity for the custom value and buy the product

5. Confirm the sale order

a Production order with the selected value of Component will be created
