Additional cost Freight, CST is calulating in MIRO for 10.3% not requied

Hello Team,

Additional cost Freight, Octroi, and CST we have assigned as NonInventorised and we get result in PO and GRN correctly for G/L account wise. Example. Freight value =10, Octroi= 7.51 and Cst value = 15.18

it shows G/L account wise in GRN and it is OK, but when we try to MIRO, system is calculating addition tax on freight, Octroi and CST for 10.3% means it comes 1.02.01 for Fright, Octroi .75.02.01 and CST 1.52+ .03+.02 but actually we don't want this calculation in MIRO. Because of this we are getting the wrong result.

Please suggest me the any configuration or any steps which we can follow.

Thanks
