Hi,

Where can i set the account to facilitate the difference rate for mass addition, if there's different rate between Purchasing and Invoice

ex:

Rate on 8th June = IDR 13,637

Rate on 15th June = IDR 13,291

PO on 8 June 2016, with price IDR 40,000,000 = $ 2,933.20

Matching to Invoice on 15th June = $  3,009.56

When we run prepare and mass addition, in the GL the journal shows amount

Dr. Asset                 $3,009.56

Cr. Asset Clearing      $ 2,933.20

Cr. Asset Clearing      $ 76.36

I notice, the amount $76.36 came from the difference rate between PO and Invoice

Is it possible to set the account, so that don't enter to account asset clearing, but into another account?
