Rounding Difference in Process Order

Dear SAP Gurus,

I need to explain accounting how rounding works when consuming the components of BOM while confirmation of process order. We have two very similar packaging products with 'EA' as base UOM in one BOM.

Comp A Target = 2.222 EA Actual = 3 EA

Comp B Target = 99.283 EA Actual = 99 EA

We don't have any rounding profile and value. I have compared the material master and recipe for both comp A and B but can't find why one component is rounding up and other is rounding down.

Any help would be highly appreciated.

Thanks in advance.
