Our product cost changes rapidly. I want to update the cost of a manufactured product automatically by running the Compute Price from BOM server action, when the cost of a component of its BOM is changed.
Odoo is the world's easiest all-in-one management software.
It includes hundreds of business apps:
- CRM
- e-Commerce
- Comptabilitat
- Inventari
- PoS
- Projectes
- MRP

Thank you, Nomad_King! I have found the solution based on your reply. Here is the Automated Action Python Code for the On Update trigger of the Product model:
# Load the related BOM records for the current product
rec_boms = env['mrp.bom.line'].search([('product_id', '=', record.id)]).mapped('bom_id')
for bom in rec_boms:
# Load the referencing product of the BOM
for ref_prod in bom.product_tmpl_id:
prod = env['product.product'].search([('id', '=',
ref_prod.id
)])
# Call the Update Price from BOM method to update the product cost
prod.button_bom_cost()
Hi I got error like this.
Error:

The above exception was the direct cause of the following exception:

You can create a scheduled action. This worked for me in odoo v14.
# Load all BOM records for all the products
rec_boms = self.env['mrp.bom'].search([('product_tmpl_id', '!=', False)]).mapped('product_tmpl_id.id')
# Load the referencing product of the BOM
for ref_prod in rec_boms:
prod = self.env['product.template'].search([('id', '=', ref_prod )])
#Update Price from BOM method to update the product cost
prod.button_bom_cost()

which Odoo version are you on?
I am using version 15
For others reading this isn't always necessary as Odoo can update the cost automatically based on the costs of purchased components that are used and the time they are used. Remember that the BoM is the recipe, not what is used. If people stick to the recipe all the time and always use the newly purchased components this strategy will work fine. If you sometimes use components in stock and/or ever use more or less components than the BoM plans for, then this option won't be better than having Odoo do it based on a FIFO or AVERAGE cost for your products (components and finished goods). With this approach, the things you make in March using products you paid for in January will be costed as if you made them using products you paid for in March.
Thank you for clarifying, Ray! Typical manufacturing businesses should utilize the Odoo built-in features whenever possible. My client is an EOM manufacturer for highly customized products. They don't stock inventory. When a client wants to place an order, they always get the up-to-date cost from vendors first. Then, they will add their manufacturing cost and margin on top in their price quotation to the client. Therefore, they cannot use the built-in features to compute cost from previous POs. Especially under the current US market situation where raw materials cost increases rapidly. Therefore, they need this customization to ensure that their quotation will not go below desired margin.
