There are 2 ways of bringing it one in MM & other is FI pricing procedure.See screen shot
If MM, configure condition type in M/06 & then assign in your pricing procedure in M/08
If you need in FI side then configure your condition type in OBQ1 & assign in OBQ3 & create a tax code in FTXP then it will flow in FI condition tab in PO.Create the account key based on whether it is Deductible or Non deductible in OBCN
Regarding printing part write the FS the ABAPer will do the rest.
