When returning a kit, the margin of the related SO decreases
To reproduce the issue:
(Need sale_management)
1. In Settings, enable "Margins"
2. Create a Product Category PC:
- Costing Method: FIFO
3. Create two products P_kit, P_compo:
- Both:
- Type: Storable
- Category: PC
- P_compo:
- Cost: 10
4. Update P_compo quantity: 1
5. Create a BoM:
- Product: P_kit
- Type: Kit
- Components: 1 x P_compo
6. Update P_kit's cost
7. Create and confirm a SO with 1 x P_kit, unit price = $100
- Note that the margin is correct: $90
8. Process the related picking
9. Create a return R
10. Go back to the SO
Error: the margin is now $80
When computing the cost of the kit, the move linked to R are considered.
Therefore, the cost becomes $20 and thus the margin becomes $80
