Click Management from the menu and then Operational Benchmarking and then Cost of Production to go in to the Cost of Production module. In the top left corner of the window on the right, you will see Allocate Commodities. Click on this to open up another window where all of your expense entries are listed. At the top of this list, you can choose the year in which the expenses were recorded. On the top right hand side of this window, you can assign the production period to which that expense belongs - which would be the previous year in this case.
