Tax indicator determination

Hello all,

i have one question in relation with tax indicator determination in sales and distribution. My situation is this:

I have a sales document with the same sold-to-party, bill-to-party and payer (country from EU= 'FR''); and different ship-to-party (country diff. to EU = 'CN'). I determine tax and Country of sales tax ID number with bill-to-party. And i want that the tax indicator was determined by bill-to-party.

In MWST condition register, SAP determines tax from country 'FR' (OK) but the register has field 'destination country' and because of that it determines tax indicator from ship-to-party.

I want tax and tax indicator from FR. How could i change it?
