Hi Rohit,
Can you pls chk these settings once again?
OBBG - Assigning of tax procedure to country
OB40 - chk tax type ( V- input & A - ouput ), GL Account with tax code combination. If not maintained so pls maintain this one.
FTXP - Pls chk the Country, tax procedure, GL assignment combinations properly. This settings need to match with OB40 data.
OX10 - check the plant code created here. Is the same is assigned in the PO?
FV11 -Please check the condition types maintained with the tax type i.e for material/plant/vendor. Also maintain the tax code with the correct tax type here.
Revert us if you still face any issues.
Thanks & Regards,
Lakshmi S
