Decimal problem while coverting base unit to produciton unit in order confirmation

Hi Experts,

Need your help here.

The base unit of product is L, while production unit is KG. 850 KG = 1000 L.

Order created for 28000 KG. as per calculation, qty is converted to 32941.1764705882 L, and hence rounded to 32941.176.

When performing confirmation via COR6N, Yield qty is shown as 32941.176 L. However, in the goods movement screen, the qty is converted to 27999.999 KG. Is there any way to populate 28000 KG?

We don't want to touch master recipe as they are already created with unit L. Changing them to KG will be a massive effort.

Appreciate some other suggestions.
