Different plants at different countries in same company code

Hi experts,

We have configured two plants (CA and US) for the same company code (CA). The company code CA uses a calculation procedure TAXCAJ (with tax jurisdiction code).

When we create a PO for a US plant and execute the transaction MIRO (invoice) an error message is displayed: Jurisdiction code is not defined for calculation procedure TAXCAJ. The system is considering a country key assigned in plant US.

I tried to activate Plants abroad, but it is not possible. The plants abroad solution was only developed for countries without tax jurisdiction codes.

Could someone help me, please?  Any sugestion?

Thanks!
