Freight amount and qty not picking in MIRO for Import PO

Hi Experts,

When i doing MIRO for Import PO , I am getting only Line item for Freight vendor but qty and and value is not picking but i have done miro against main vendor , there is no problem , problem is coming only for freight vendor. main and freight vendor are not same. I will not cancel the document bcz material is already sale out.

Is there any option to adjust freight amount in miro and i will do manully enter all the amount and quantity.

Regards

Rahul
