How to do the cost update process for the freight cost in OPM?

 Hi,

We are having 11.5.10.2 instance and OPM org's. For doing inventory transfer through ISO other than the material cost freight cost also there. For this we have done one custom form for transportation where once delivery happens freight amount will generate as provision Cr (knock off after invoicing to transporter) and clearing account for Dr for know intrasit frieght for month end reconciliation.

What is the way for that freight to be inventorise by product wise in OPM. And Clearing account should come for Cr for knock off the account at provision time.

What are the way's to do the freight cost tobe inventorize?
