This is another example of using Automated Actions. When a Sales Order is confirmed this will create tasks (on a project) for each of the sales order lines.

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

Data to Write:

Python expression:

record.order_id.name + ' / ' + record.product_id.name

This is a very simple example and it can be adapted quite easily.

• You could write other information to the task by changing the Python expression:

record.product_id.name + ' / ' + str(record.product_uom_qty)

(that will write the Product name and quantity)

Note that Odoo already has standard functionality to create projects or tasks for service items, and that may be a simpler way to achieve the same thing. This is described in more detail here.
