In Pharma manufacturing, there are several items which are purchased and stored in "KGS". In some BOMs, the same item quantity is defined in Milligrams. So, in such case if, KGS is the base unit of measure, and we need to add an alternate unit of measure in "Item Unit of measure" for "MG", it is not possible to define a "Qty. Per Unit of Measure" as 0.000001 due to the limitation of 5 decimals. Microsoft should consider increasing the number of decimals in "Qty. Per Unit of Measure" and all other pages wherever applicable so this issue will be avoided.
