We have a UOM conversion from CS to POUND (i.e. 1 case = 30 pounds), and at some point may want to change it so that 1 case = 28 pounds.
Normal scenario, all transactions are done at the CS (primary UOM) and the weight is only used in calculations to print on shipping documents.
Is there any harm in just changing the 30 to 28 when that time comes? Again, there are no transactions that reference the weight, no PO's, no SO's, no financials, etc.
