Realized exchange rate difference in local and group currency

Hi Friends,

For a company code with local currency as Euro and group currency as USD, the setting in TR code OB22 for group currency is: Translation taking first local currency as a basis. When the open items are cleared, SAP posts difference in local currency and group currency. Sometimes, document currency is also group currency i.e. USD. The realized exchange difference is posted in Euro but it is not converted from Euro to group currency. Instead, system just calculates difference in group currency by comparing the value in group currency at the time of original transaction and when the transaction is cleared. Does anyone have dealt with such requirement and is there a way to be able to translate realized exchange differences from local to group currency?

Thanks and regards,

Pinky
