Hello CPS,
The Stock Transfer function allows you to assign additional cost to items when posting the Transfer.
There are 2 fields that allow this. The "Cost to prorate" field in the Header (Stock Transfer) window and the "Additional cost" field in the Detail (Edit Stock Transfer) window.
Sounds like the Additional cost field is the one you want as it allows you to assign the cost to the specific item in that window.
On the other hand, the Cost to prorate field would assign the amount entered to all items in the transfer by prorating the amount based on the percentage of total cost (entire transfer cost for all items) that each individual item transfer cost represents.
Hope that helps.
Pete
