Hey Emanuel

The `hr_attendance_report_theoretical_time` functionality is part of Odoo 15 and newer. See "hr.attendance.overtime" model for reference

I highly recommend you to upgrade your Odoo instance.

To detect missing attendances there is https://www.odoo-wiki.org/hr-attendance-missing.html#hr-attendance-missing for Odoo 15 to 17. Missing attendances is supported by Odoo 18.

Cheers, Janik

Hello Contributors,

We are using the module hr_attendance_report_theoretical_time for checking our employees working time balance (extra or minus hours), but are facing performance issues (on Odoo 14 at the moment).

We’ve noticed that the report in the module can be slow, especially when handling a large number of attendances. In our setup, it computes all attendances since we started using the module, which significantly impacts performance.
While we sometimes need to analyze attendance over a limited period (e.g., the current year or semester), most of the time we need to retrieve the complete balance of an employee since their start date to assess total (=current) extra or missing hours.

Questions for the Community
  1. Have others experienced similar performance issues with this report?
  2. How do you optimize performance? Have you implemented any workarounds?
  3. Would there be interest in adding a mechanism to store computed balances at a pivot date to reduce the number of records processed?
  4. Do you use another method for computing the total extra hours of any employee? What is your approach?
Any insights or suggestions would be greatly appreciated!

Thanks,
Emanuel
