Bom UOM vs Inventory UOM

Hi, I would like to know the impact and difference between both UOM? I want to set up Bom UOM with 2 decimals and Inventoru UOM with 2 or 4 decimals. Is it ok? where are différences? How can I set up my End item Bom and subcomponent Bom to make sure that they are from costing point of view? Thanks

The BOM UOM is used when you add it as a component to a BOM.

Your decimal place difference is no issue as you will have to configure the conversion and you will set it how you want.

Run the calculation of the parent and define the component at the correct rate to ensure it is costed correctly.

Thanks Adam
