Rounding difference between PO and GR

[ricky_liu19]

Hi experts,

I have a PO for one material which PO quantity is 525 and Net value 252350.18. While I do GR for this material, my GR quantity is 520, but the net value shows on Amt in Loc Cur is 249946.84.

I have calculated the amount using the following formula:

GR qty * (PO net value / PO qty)

=520 * (252350.18 / 525) = 249946.845

Can anyone tell me why the amount is not rounded to 249946.85, but to 249946.84？(There is no foreign currency in this PO)

Regards

Ricky
