Management of additional currency during data migration

Hi Experts,

We are in the process of implementing a new customer. We have successfully migrated existing customer data. Now, we want Navision to automaticly generate Reporting Currency data (additional currency data).

In Setup->General Ledger Setup->Reporting, we selected the reporting currency. Then a message announcing that a batch job is displayed. On validation of this message box, nothing happens. No data related to Additional Reporting Currency is generated.

But surprisignly, when a new transaction is posted on a ne, LCY and Reporting currency data are created in the GL.

Anyone has an idea how to sort out this issue ? Thanks in advance
