calicurate of sales unit price

Hi all,

VBRP has not unit price.

I want to calicurate of sales unit price.

Field NETWR comes from unit price(user input) * quantity(user input) and round down.

Case 1. NETWR(net value) / FKIMG(quantity) = 'x'

and 'x' round down at the third decimals.

Like this case, Are there possibility 'x' distinct from first unit price?

Regards,

Saeko
