Impacts of new company code currency

Hi Gurus,

We have a company code which is setup 2 months back. We have it setup with USD and this company code is assigend to a controlling area in one -one basis. So it should be fine . But now business want to change the CCode currency. All G/L and master data is created with USD. What would be the impacts if we change currency of master data also into new currency? We have no New-GL . We used special ldgers but just for a specific activity.

Any thoughts ?

Thanks,

GB
