Transactions with Pct. exempt from sales tax

Hello,

I have a question regarding the setting Pct. exempt from sales tax on sales tax codes in AX 2009.

A transaction with this sales code will generate the following transactions.

1. A vendor invioce arrives with the amount of 1250 incl. 25% VAT 

2. In Denmark though, it is only 50% of the incoming tax that is deductible for certain goods and services which means that only 125 DKK (50% out of 25% of 1000) is posted to the VAT account.

3. The rest of the tax-amount (125 DKK) is created as a separate posting to the expense account.

My question is if there are any setting in AX 2009 that creates one transaction with 1125 DKK instead of two transactions with 1000 and 125?

Regards
