When i create a process order, one of the material was calculating as 900KG but the requirement was only 884KG. Then i found out in Units of measurement it was define as 225 KG = 1 ea. In the rounding value field in MRP1 it was 4. I thoought its calculating as 900 because of this 225 x4 = 900.
So i removed th rounding value 4 and thn i put it as 1. Now if i create process order it is taking correctly as 884 KG but when itry to assign batch manually itis again changing as 900. I thought some settings in batch determination. Can someone throw light on this please.
