Context
We are using the Contracts Management functionality in Odoo 9 for managing our Consulting Services, using the Products set as a "Service" and "invoice based on time and material" and tracking with "create a task and track hours", then assigning a Project as the analytic account on the Sales Order. We need to capture consultants time against these auto-created tasks through the timesheets functionality (for ease of use, security and approval processes).
Problem
The Timesheet module doesn't seem to allow tracking of time against a task on a project, only against the project as a whole. Which seems odd given the time tracking method used in the product, project and sales order for invoicing. I'm not sure if this is a setting that I'm missing, or a module/extension I need to install, or something else entirely.
Tried So Far
Tried the various Product configurations for billing time and expense, though the current configuration is really the only way that our process works. None of these made any difference.
Set the Project Settings to: "log work activities on tasks"
Looked for module to install, but could only find one suggested in this post: https://www.odoo.com/forum/help-1/question/enter-time-by-task-not-project-on-hr-timesheet-48780 - however this is not available for the latest v9 release.
Checked the list of activities that come out of the timesheet entry screen (in the Activities page) and found that the task is available to fill in at this point
Quickly looked at possibility of adding the task field from the Project in the timesheet entry form (assuming it would be available as per point 4 above), however this field isn't available in the Timesheet Data Object.
Any ideas?
