Incremental Backflush consumption

Hi,

Is it normal that the incremental backflush consume the ingredient with decimal even if my formula set up are setup as "integer"  and "rounding up"?

I see the Integer and rounding up when i create the batch, the planned quantity is scale related to the formula and rounding up.

But when I do incremental backflush, the actual quantity are consume with decimal.

When the UOM is UN, we don't want a decimal consumption.

Does it exist another setup to get the right UN amount ?

Thanks

François
