Issue:
1. User is unable to scan the unit from backend production where MES will show the "Serial number child not matched with the serial number parent".
2. This is because the unit is checked the checkbox "same as parent serial number" under page Product Tree.
Solution:
1. User need to uncheck the checkbox "same as parent serial number" under page Product Tree.
2. User need to check the "Update Product Version" and "Update Tree Version" checkbox under page Identity Change.
