All excise values are ZERO in Purchase order

Hello

We are using tax procedure TAXINJ procedure for Tax calculation.

Created the Purchase order for a material, entered the tax code in invoice tab system will not shown BED(JM01 condition) ECESS and SECESS values.

we have checked the Material and chapter id combination is correct available and Vendor excise details, here also vendor is excisable. checked the excise indicator for plant. plant also excisable.

maintained the excise tax rate infront of chapter id in J1ID....

But still PO is not showing any tax values in PO, all the values it is showing is ZERO.

Do the needful.
