Currency Conversion differences to specifc account during Voucher Entry

Hello JDE Team,

We have set up the AAI in JDE to post currency conversions differences in a specific account in 100.7000.TEST.

When we enter voucher and there is a different change rate, the difference amount goes to a PPV account (100.70010.PPV) instead of the profit account.

I would like to understand how currency conversion accounting works during voucher entry and where the setup is done.

Regards,
Prateek
