Tax code A0 in procedure YTAXIN is invalid.

Hello SAP Gurus,

I have maintained a tax procedure YTAXIN in OBQ3 which is a copy of TAXINN.

I have completed a sales process (Sales Order>Delivery> Billing) when I am trying to create Excise Invoice (TCode J1IIN) with reference to Billing Document the system is showing an error

Tax code A0 in procedure YTAXIN is invalid.

The tax code A0 is maintained in a different Tax Procedure ZTAXIN, then why the system is picking it when I am creating Excise Invoice.

Thanks in advance,

Ashutosh
