+# timesheet_timesheet_analysis_report
+
+Add a `timesheet_id` Many2one relation to the `timesheets.analysis.report` model, linking each analysis report line back to its source `account.analytic.line` record. This allows filtering and grouping the Timesheet Analysis Report by individual timesheet entry.
+
+## Installation
+
+Use the standard Odoo module installation procedure to install `timesheet_timesheet_analysis_report`.
+
+**Dependencies:** `base`, `hr_timesheet`
+
+## Configuration
+
+No specific configuration is required. The `timesheet_id` field is automatically available on the Timesheet Analysis Report once the module is installed.
+
+## Usage
+
+After installation, the Timesheet Analysis Report (`timesheets.analysis.report`) includes a new **Timesheet** field. You can use it to:
+
+- **Filter** the analysis report by specific timesheet entries.
+- **Group by** timesheet to aggregate data per individual time entry.
+- **Search** for report lines linked to a particular timesheet record.
+
+## Known Issues / Roadmap
