When confirming a SO, if a line uses a different UoM than the default
UoM of the line product, the computed cost will be updated to the
product unit cost.
To reproduce the error:
1. In Settings, enable:
- Units of Measure
- Margins
2. Create a product P
- Sales Price: $100
- No customer taxes
- Cost: $50
- UoM: Units
3. Create a SO
- Add P
- Set the line UoM to 'Dozens'
4. Display the order line field "Cost"
- [Note] As you can see, since UoM is 'Dozens':
- Unit Price: $1200
- Cost: $600
5. Confirm the SO
Error: Line cost becomes $50 (the cost of one P-product). Since the UoM
of the line is 'Dozens', Cost should be $600 (as before confirming the
SO). As a result, this error creates incorrect data in the margins
(95.83% instead of 50%).
