Re: Multiple fiscal positions on partners


Just to let you know that fiscal position aproach is valid for spain, the
way it is defined by now.

Here, we have got fixed taxes for different kind of products. So each
product needs a different tax % to be applied.
After that, the taxes are translated to the correct ones depending on
customer fiscal position.

No extra developments needed for our country regarding to fiscal position
or taxes.
Just my 2 cents.

>>              Product Cost     Tax A     Tax B     Tax C        Total
>> Location A       X              X         X         X            X
>> Location B       X              X         X         X            X

>> - Taxes may or may not be part of the product price. In Brazil usually

>>         Usually a=b=c, but not ALWAYS!
