Unable to calculate overhead rule cost in cost management

Content

Our business needs to add a freight to a PO in OSP manufacturing, as there is no direct way we have created a "overhead accounting rule" and assigned a rate to it as shown in screen shot. I ran all the transfer ESS jobs and create cost accounting distributions. When I am reviewing the cost accounting distributions I couldn't see the overhead distribution/cost.

Can any one help me out on this?
