🐛 Error Fixed:
- AttributeError: 'VierteljahresNachweis' object has no attribute 'completion_percentage'
- Line 5347 in destinataer_export view was calling completion_percentage()
- Corrected to call get_completion_percentage() which is the actual method name
✅ Export functionality now works correctly for destinataers with quarterly confirmations
The error occurred when exporting a destinataer that had quarterly tracking data.
All quarterly confirmation completion percentages are now properly exported.
