Exchange rate difference on VAT amount to be posted on VAT account

Hi Gurus,

we have a requirement for a Tukish company, to post Exchange rate differences calculated on VAT amount by MIRO on the same VAT account.

I checked OBYY T code, but I cannot change accounts here, because Chart Of account is in common with other companies. I'm not sure that a substitution in this case may work.

Is it possible to drive the posting of Exchange rate differences on vat amount through company code, choosing a different account from OBYY?

Thank you in advance for your suggestions.

Stefano
