1. Understanding Odoo’s Default Behavior:
In Odoo 16/17/18 Enterprise, the General Ledger Report pulls journal entries from posted accounting moves, based on applied filters such as:
- 
Date range
- 
Journals selected
- 
Target moves (All entries or Posted only)
- 
Accounts selected (if customized)
If the report shows incorrect or missing data, it usually comes down to one of these factors.
2. Step-by-Step Troubleshooting:
✅ Ensure You Have Data:
- 
Navigate to Accounting > Journal Entries and verify there are posted moves for the selected date range.
✅ Check Report Filters:
- 
From Accounting > Reporting > General Ledger, review:
- 
Date range: Ensure it’s broad enough.
- 
Target moves: Select All Entries if you're debugging.
- 
Journals/Accounts: Try not filtering anything first.
- 
Analytic filters (if applicable): Remove these unless needed.
 
✅ Posting Status:
- 
Only posted entries appear in the General Ledger unless “All entries” is selected.
- 
Draft journal entries will not show.
✅ User Access Rights:
- 
You must have Accountant or Advisor rights to view full ledger reports.
- 
Limited users may see blank or partial reports.
3. Custom Reports or Broken Views:
If you’ve installed a custom module that modifies reporting, it may:
- 
Override filters
- 
Change report logic
- 
Break the report if not properly migrated
Temporarily disable custom modules and check if the report works in vanilla Odoo.
4. Try in Developer Mode:
- 
Activate Developer Mode (from Settings > Activate Developer Mode).
- 
Check for any JS or server traceback errors in the browser console or logs.
