account determination - exchange rate and valuation

Hello All,

we have a problem concerning our account determination for differences in exchange rate and valuation. When clearing open vendor items in foreign currency, a percentage of the difference goes to our exchange rate difference account (correct), but the other part of our difference goes to the account we have configured for valuation (incorrect).

Before, we had, in "Account Determination for OI Exch.rate differences" (transaction FBKP) , the following configuration for all our accounts in foreign currency:

Exchange rate difference realized:

Loss: 66800000

Gain: 76800000

Valuation

Val Loss: 66800100

Val Gain: 13600000

Bal sheet adj: 40099999

Now, we have the same accounts,except for "Bal sheet adj", for which we have 5 different accounts depending on the account to be valued. This change shouldn't have any effect, but since then, every time we clear an open item (KR and KZ), one part of the difference goes to an exchange rate difference account, while another part goes to valuation, when this last account should only be used when running F.05.

Any help?

thanks

Daniel
