This is similar to creating a BOM but adds some extra options (kinda). The requirement is to create an Analytic Account for each Sales Order – and use it on the order. This replicates the standard functionality in Odoo to automatically create an Analytic Account for each project.

Enable Developer Mode and navigate to Settings / Technical / (Automation) / Automated Actions:

• Model = Sale Order                                            
• Action To Do = Create a new Record
• Trigger Condition = On Creation       
• Create/Write Target Model = Analytic Account
• Link using field = Analytic Account (sale.order)   
  • analytic_account_id                        

Data to Write

Record	Evaluation Type	Value
Analytic Account (account.analytic.account)	Python expression	record.name
Customer (account.analytic.account)	Python expression	record.partner_id.id

Problem

Unfortunately there’s a problem with this. It isn’t possible to enter the “Link Using Field” because the domain is incorrect in the XML. It’s a bug and it has been logged in GitHub (spoiler alert: they didn’t fix it, but I found a way to do it and I’m not even a Python programmer).

The problem is in the Form View for Server Action (base.view_server_action_form). This is the domain (from Odoo 12):

domain="[('model_id', '=', model_id),
         ('relation', '=', crud_model_name),
         ('ttype', 'in', ['many2one'])]"

1. The model_id comparison is correct
2. The crud_model_name comparison is wrong
   • It could be removed (which would allow selection of fields that do not link to the correct Model)
   • Or it can be fixed using Odoo Studio, as explained here
   • Or you could use the download / upload tool (Model ir.actions.server) to enter the correct value.
3. In Odoo 13 the type has been expanded to include one2many and many2many, but that is not the issue here (and if line 2 was correct this would be redundant).

You can fix this yourself as explained here

Another technique

This is another way to create a record in another Model (but doesn’t solve the linking problem).

• Model = Sale Order                                            
• Action To Do = Execute Python Code
• Trigger Condition = On Creation                                       

Python Code

env['account.analytic.account'].create({
         'name':record.name,
         'partner_id':record.partner_id.id
})
