+# Time Tracking - Billed Via Hub Order ID
+
+## Oversigt
+
+Implementeret tracking af hvilken Hub ordre (og dermed e-conomic ordre) hver tidsregistrering er blevet faktureret gennem.
+
+## Database Ændringer
+
+### Migration: `060_add_billed_via_thehub_id.sql`
+
+Tilføjet nyt felt til `tmodule_times` tabellen:
+
+```sql
+ALTER TABLE tmodule_times ADD COLUMN billed_via_thehub_id INTEGER;
+ALTER TABLE tmodule_times 
+    ADD CONSTRAINT tmodule_times_billed_via_thehub_id_fkey 
+    FOREIGN KEY (billed_via_thehub_id) 
+    REFERENCES tmodule_orders(id) 
+    ON DELETE SET NULL;
+CREATE INDEX idx_tmodule_times_billed_via_thehub_id ON tmodule_times(billed_via_thehub_id);
+```
+
+**Felt beskrivelse:**
+- `billed_via_thehub_id`: Hub ordre ID som tidsregistreringen er faktureret gennem
+- Foreign key til `tmodule_orders.id` 
+- Via Hub ordren kan man finde `economic_order_number` som er ordrenummeret i e-conomic
+
+## Kode Ændringer
+
+### 1. `app/timetracking/backend/models.py`
+
+Tilføjet felt til `TModuleTime` Pydantic model:
+
+```python
+billed_via_thehub_id: Optional[int] = Field(None, description="Hub order ID this time was billed through")
+is_travel: bool = False  # Også tilføjet manglende felt
+```
+
+### 2. `app/timetracking/backend/economic_export.py`
+
+Opdateret `export_order_to_economic()` til at sætte `billed_via_thehub_id` når ordren eksporteres:
+
+```python
+# Marker time entries som billed og opdater billed_via_thehub_id
+execute_update(
+    """UPDATE tmodule_times
+       SET status = 'billed',
+           billed_via_thehub_id = %s
+       WHERE id IN (
+           SELECT UNNEST(time_entry_ids) 
+           FROM tmodule_order_lines 
+           WHERE order_id = %s
+       )""",
+    (request.order_id, request.order_id)
+)
+```
+
+**Vigtig note:** vTiger opdateres også via `update_timelog_billed()` som sætter `billed_via_thehub_id` i vTiger's Timelog records.
+
+### 3. `app/timetracking/backend/order_service.py`
+
+**FJERNET** for tidlig status opdatering:
+
+```python
+# BEFORE: Time entries blev sat til 'billed' når Hub ordre blev oprettet
+# AFTER: Time entries forbliver 'approved' indtil e-conomic eksporten er succesfuld
+```
+
+Nu opdateres `status='billed'` og `billed_via_thehub_id` KUN i `economic_export.py` efter succesfuld eksport.
+
+### 4. `app/timetracking/backend/vtiger_sync.py`
+
+**BESKYTTELSE MOD OVERSKRIVNING:** Tidsregistreringer med `billed_via_thehub_id` opdateres IKKE ved sync:
+
+```python
+# Update only if NOT yet approved AND NOT yet billed
+result = execute_update(
+    """UPDATE tmodule_times 
+       SET description = %s, original_hours = %s, worked_date = %s,
+           user_name = %s, billable = %s, vtiger_data = %s::jsonb, 
+           sync_hash = %s, last_synced_at = CURRENT_TIMESTAMP
+       WHERE vtiger_id = %s 
+       AND status = 'pending' 
+       AND billed_via_thehub_id IS NULL""",
+    ...
+)
+```
+
+Dette sikrer at allerede fakturerede tidsregistreringer forbliver låst og ikke overskrevet af vTiger sync.
+
+## Workflow
+
+### Før ændringerne:
+1. Godkendte tider → `status='approved'`
+2. **Opret ordre** i Hub → `status='billed'` ⚠️ (for tidligt!)
+3. Eksporter til e-conomic → `economic_order_number` sættes på Hub ordre
+
+### Efter ændringerne:
+1. Godkendte tider → `status='approved'`
+2. **Opret ordre** i Hub → tider forbliver `status='approved'`
+3. **Eksporter til e-conomic** → `status='billed'` + `billed_via_thehub_id` sættes
+4. vTiger opdateres også med `billed_via_thehub_id`
+
+## Data Relations
+
+```
+tmodule_times.billed_via_thehub_id 
+  ↓ (foreign key)
+tmodule_orders.id
+  → tmodule_orders.economic_order_number (e-conomic ordre nummer)
+  → tmodule_orders.economic_draft_id (e-conomic kladde ID)
+```
+
+## Queries
+
+### Find alle tidsregistreringer for en e-conomic ordre:
+
+```sql
+SELECT t.*, o.economic_order_number
+FROM tmodule_times t
+JOIN tmodule_orders o ON t.billed_via_thehub_id = o.id
+WHERE o.economic_order_number = '12345';
+```
+
+### Find tider der er faktureret via en specifik Hub ordre:
+
+```sql
+SELECT * FROM tmodule_times 
+WHERE billed_via_thehub_id = 123;
+```
+
+### Find tider der IKKE er faktureret endnu:
+
+```sql
+SELECT * FROM tmodule_times 
+WHERE status = 'approved' 
+AND billed_via_thehub_id IS NULL;
+```
+
+## vTiger Integration
+
+vTiger's `Timelog` records opdateres også via `app/timetracking/backend/vtiger_sync.py`:
+
+```python
+async def update_timelog_billed(self, vtiger_ids: List[str], hub_order_id: int):
+    payload = {
+        "elementType": "Timelog",

+```
+
+**Note:** `cf_timelog_invoiced` (IS BILLED) feltet i vTiger kan vi IKKE ændre fra Hub (vTiger begrænsning), men vi opdaterer vores eget `billed_via_thehub_id` felt.
+
+## Testing
+
+Migrationen er kørt og verificeret:
+```bash
+docker exec bmc-hub-postgres psql -U bmc_hub -d bmc_hub -c "\d tmodule_times"
+# Viser: billed_via_thehub_id | integer med foreign key
+```
+
+## Deployment
+
+1. Migration er kørt på dev (060_add_billed_via_thehub_id.sql)
+2. Kode ændringer deployed i samme commit
+3. Eksisterende tidsregistreringer har `billed_via_thehub_id = NULL`
+4. Fremtidige eksporter vil populere feltet korrekt
