We are in the process of onboarding onto Odoo and have encountered a critical issue regarding the setup of Unit of Measure (UoM) ratios, specifically for units smaller than the reference UoM. Initially, we incorrectly applied the same formula used for units larger than the reference to calculate these ratios, resulting in incorrect data being saved.

Despite our efforts to rectify this by archiving affected products and attempting to cancel their transfers through returns, we are unable to modify the UoM ratios. Whenever we attempt to make changes, we receive the following error message:

Invalid Operation: You cannot change the ratio of this unit of measure as some products with this UoM have already been moved or are currently reserved.

Could anyone please provide guidance on how we can update the UoM ratios despite the products having been moved or reserved? Any alternative solutions or workarounds would also be greatly appreciated.
