Supplementary Unit Quantity

Hello Experts,

I am declaring products that weighs less than 0.500G / 500MG. In such case the system throwing error UoM not determined for the statistical quantity. The supplementary unit quaintly(KG) converts to '0' (Zero) which is preventing to process the message.

I need some suggestions/help how can I achieve to round up the supplementary unit quantity to 0,001KG whenever the quantity or weight of the product is less than 0.5G/500MG?

Message: M0410 and M0910.

Thanks in advance.
