Want to Know how can we overcome Foreign Exchange Gain or Loss account at the Receipt level.

We are in 11i environment. we have a accouting structure as Comp. Dept. Account

let us say we have defined the Foreign exchange gain or loss at the system options level as 100.000.1234. we are using same bank account for all the depts and Gain or loss account defined at the bank account level also same as the system options. i.e 100.000.1234.

Now let us say we have entered the Foreign exchange Invoice with the Dept as 110. Tht means Receivables will be as 100.110.3456.Now we have received a receipt for this and when we apply this receipt against the same invoice system is creating foreign exchange gain or loss accounting entry with the dept as 000 even though we have created invoice with the dept as 110.
