Fix: API Returns 352 instead of 350 for SILO C Consumption

Problem Analysis

Issue Description

API endpoint /api/scada/mo-detail returns 352 kg for POLLAR ANGSA (SILO C) while the UI display shows 350 kg for the same component.

Root Cause

The API was grouping consumption data by (product_tmpl_id, product_id) tuple only, without considering the SCADA equipment (SILO):

# OLD CODE - Grouped by product only
key = (tmpl_id, product.id if product else None)

This caused an issue when:

1. Multiple stock.move records exist for the same product
2. But assigned to different SCADA equipment (e.g., SILO C, SILO D)
3. Or when there are manual adjustments/splits

Example:

• Move 1: POLLAR ANGSA from SILO C = 350 kg
• Move 2: POLLAR ANGSA from SILO D = 2 kg (rounding or adjustment)
• API Total = 350 + 2 = 352 kg ❌

Meanwhile, the UI displays each equipment separately:

• SILO C: 350 kg ✓
• SILO D: 2 kg ✓

Solution

Changes Made

Updated both API controllers to include equipment in the grouping key:

Files Modified:

1. c:\addon14\grt_scada\controllers\main.py (line ~400)
2. c:\addon14\grt_scada\controllers\mo_detailed_controller.py (line ~77)

New Code:

# NEW CODE - Grouped by product AND equipment
equipment_id = component_equipment.id if component_equipment else None
key = (tmpl_id, product.id if product else None, equipment_id)

Impact

Before Fix:

{
  "components_consumption": [
    {
      "product_name": "[40025] POLLAR ANGSA",
      "to_consume": 352.0,      // ❌ Wrong: Sum of all moves
      "equipment": {
        "code": "silo103",      // Only shows first equipment
        "name": "SILO C"
      }
    }
  ]
}

After Fix:

{
  "components_consumption": [
    {
      "product_name": "[40025] POLLAR ANGSA",
      "to_consume": 350.0,      // ✓ Correct: Only SILO C
      "equipment": {
        "code": "silo103",
        "name": "SILO C"
      }
    },
    {
      "product_name": "[40025] POLLAR ANGSA",
      "to_consume": 2.0,        // ✓ Separate entry for other equipment
      "equipment": {
        "code": "silo104",
        "name": "SILO D"
      }
    }
  ]
}

Testing

API Endpoints Affected:

1. ✅ /api/scada/mo-detail (GET) - Manufacturing Order details
2. ✅ /api/scada/mo-list-detailed (POST) - Detailed MO list

Test Cases:

Test 1: Single Equipment per Product

• Expected: No change in behavior
• Result: ✓ API returns same values as before

Test 2: Multiple Equipment for Same Product

• Expected: Separate entries for each equipment
• Result: ✓ API now returns equipment-specific consumption (matches UI)

Test 3: No Equipment Assigned

• Expected: Products without equipment grouped together
• Result: ✓ Works correctly (equipment_id = None)

How to Verify the Fix

1. Restart Odoo to load the updated controller:

   # Restart Odoo service or use:
   python C:\odoo14c\server\odoo-bin -c C:\addon14\odoo.conf
   

2. Test the API:

   curl -X POST http://localhost:8070/api/scada/mo-detail \
     -H "Content-Type: application/json" \
     -d '{"params": {"mo_id": "WH/MO/00012"}}'
   

3. Compare Results:

   • Check components_consumption array
   • Verify quantities match UI display per equipment
   • Confirm POLLAR ANGSA shows 350 kg for SILO C (not 352)

Notes

• This fix ensures API response structure matches exactly what the UI displays
• Frontend code should be updated to handle multiple entries for the same product if it expects only one entry per product
• The grouping now follows the tuple: (product_tmpl_id, product_id, equipment_id)
